TowerBag Review: One Tower, One Skull, One Chance to Not Bore Me to Death
I've played tower defense games since before some developers were born, and TowerBag thinks it can revolutionize the genre by giving me ONE tower. ONE. Let me tell you how that worked out.

Overall Score
"TowerBag is the rare indie game that has a genuinely clever idea but stops developing it right when things get interesting."
First Impressions (Or: When Minimalism Becomes an Excuse)
So I boot up TowerBag and immediately I'm a skull. A lonely skull, according to the developer. Great. I'm having flashbacks to every other indie game that thought 'you play as a skeleton' was peak creativity. Then I see my singular tower—my ONE tower—sitting in my inventory like some kind of medieval Uber Eats delivery. The premise hits me: I have to physically move around and place this tower wherever I need it, then pick it up and move it again when the enemies change direction. This is either brilliant or the laziest game design I've seen this month. Arrow keys to waddle around as a skull, spacebar to grab my tower. That's it. That's the whole control scheme. I've used more buttons to skip cutscenes in AAA games. But here's the thing—and I hate admitting this—within thirty seconds I'm already thinking strategically about tower placement in ways I haven't since the original Kingdom Rush. The simplicity is doing something to my brain that complexity usually drowns out.
The One-Tower Hustle (AKA Actual Strategy Emerges)
Here's where TowerBag separates itself from being a joke premise and becomes an actual game. In traditional tower defense, you're spreading out multiple towers, upgrading paths, managing economies—it's tower PLACEMENT defense. This? This is tower MOVEMENT defense. I'm scrambling around like a deranged cemetery keeper, dropping my tower to blast enemies, then sprinting ahead to reposition before the next wave hits from a different angle. The enemies come from multiple directions, naturally, because the developer clearly hates me personally. What works: the constant repositioning creates genuine tension. I'm making split-second decisions about whether to let one enemy through to stop three others. I'm actually using spatial awareness instead of just clicking upgrade buttons like a zombie. What doesn't work: after you figure out the optimal movement pattern, the gameplay becomes repetitive. There's no tower variety, no upgrades, no progression system. It's pure mechanical execution, which is fine for a score-chaser but feels thin after extended play.
Visuals and Audio (Where Budget Constraints Scream Loudly)
Let me be clear: I've seen pixel art that makes me weep with its beauty. I've seen minimalist designs that feel intentional and atmospheric. TowerBag has pixel art that exists. My skull character is literally six pixels arranged in a skull shape. The tower is a brown rectangle. Enemies are colored blobs that waddle toward me with all the menace of drunk Teletubbies. Is it charming in a 'made in a weekend game jam' way? Sure. Is it memorable or visually interesting? Absolutely not. The forest background is static, the color palette is muddy browns and greens, and there's zero visual feedback beyond enemies disappearing when shot. As for audio, I genuinely cannot remember if there was sound. I think my tower made a pew-pew noise? Maybe? The silence is so profound I started playing my own music after two minutes. In 2024, when free asset stores exist and talented pixel artists are everywhere, this feels like the developer just wanted to ship something functional. Mission accomplished, I guess.
What This Game Actually Needs
TowerBag has a legitimately good core concept that's being held back by lack of development depth. Give me three different tower types—a fast shooter, a slow heavy hitter, and maybe an AOE tower—and suddenly I'm making loadout decisions before each run. Add a simple upgrade system where I can improve range or damage between waves. Include different enemy types that require different strategies beyond 'shoot them before they reach the exit.' Create multiple forest areas with unique layouts that change the optimal movement patterns. Add a combo system that rewards keeping the tower firing without repositioning. These aren't revolutionary suggestions—they're basic tower defense staples that would transform TowerBag from a clever proof-of-concept into an actually replayable game. The movement-based tower placement is genuinely innovative, but innovation alone doesn't carry a game when there's nothing to progress toward or unlock.
The Unexpected Depth in Simplicity
Despite everything I've complained about, TowerBag does something I didn't expect: it makes me think about tower defense differently. By stripping away all the economic management and upgrade trees, it highlights pure positional play. Every placement matters because it's your ONLY placement. There's a purity to it that reminds me of those old Flash games that had one mechanic and executed it perfectly. When I'm in the zone, moving my skull around and timing my tower drops, there's a flow state that emerges. The game becomes almost meditative—if meditation involved frantically preventing blob creatures from reaching arbitrary exit points. For players exhausted by tower defense bloat, there's genuine appeal here. It's the gaming equivalent of minimalist cooking: sometimes removing ingredients reveals flavors you forgot existed. The problem is that after you've tasted those flavors once, there's no reason to order the same dish again. TowerBag needed roguelike elements, daily challenges, or SOMETHING to justify repeat visits.
Rating Breakdown
Quality
6
Functional and bug-free, but let's not pretend basic pixel art and simple mechanics require a standing ovation.
Innovation
7
One tower in a tower defense game is genuinely novel, I'll give them that—haven't seen this specific brand of masochism since 2019.
Value
8
It's free on itch.io and actually kept me playing for longer than I care to admit, so fine, the value is there.
Gameplay
6
The movement-based tower placement creates genuine tension, but after twenty minutes I remembered why I usually have MULTIPLE towers.
Audio/Visual
4
Minimalist pixel art that screams 'I learned GameMaker last month' with audio that's basically non-existent.
Replayability
5
Once you've mastered the one strategy that works, you've seen everything—there's no variety to pull me back.
What Didn't Annoy Me
The one-tower movement mechanic is genuinely innovative and creates real strategic tension
Completely free and actually delivers on its simple premise without crashes or bugs
Forces you to think about tower defense positioning in ways modern TD games have forgotten
Controls are responsive enough that deaths feel like my fault, not the game's fault
Short enough that it respects my time—you can experience everything in 30 minutes
The core concept has legitimate potential if developed further
What Made Me Sigh
Visual presentation looks like a weekend prototype that never got art polish
Zero progression, upgrades, or unlockables—what you see in minute one is what you get in minute thirty
Audio design is practically non-existent, leaving the experience feeling hollow
Replayability dies the moment you've figured out the optimal movement pattern
No enemy variety means strategy becomes repetitive execution quickly
Final Verdict
TowerBag is the rare indie game that has a genuinely clever idea but stops developing it right when things get interesting. The one-tower movement mechanic works—it actually works better than I expected—and for about twenty minutes I was engaged in ways that bloated modern tower defense games haven't managed in years. But clever mechanics need content wrapped around them, and TowerBag feels like a proof-of-concept that got released before becoming a full game. It's free, it's functional, and it'll give you a brief distraction that makes you think 'huh, that's neat.' Then you'll close it and probably never think about it again. If the developer returns to this concept and adds depth, progression, and actual content, this could be something special. As it stands, it's a promising demo that I'm reviewing as a finished product. Worth trying for the novelty, but don't expect it to stick around in your mental rotation.
