This was quite fun once I got into it!
Spamming out gears in small rooms is hilariously overpowered and really fun to watch, and it was pretty fun to try to find those areas and lure enemies to them.
The visuals are nice too, I really like the background and that there's a unique sprite for when the player takes damage.
The only bits of criticism I have are that navigation felt a bit tough, it felt like I only got to the final boss because I accidentally picked the right direction, and the start of the game is rather punishing since you're in an open area with only 5 gears. Otherwise this was solid, great work!
