Very appreciate that you put the source code and first time seeing a game coded in Rust at a gamejam.  also your pixel art is rather well good but your game it's quite "slow" I expect with bubblell something more nervous (Like enemies don't move and you just have to wait in the middle without moving but promising if you want to improve it). But in any case good job ! (PS: by the way, you're not the only one who forgot the special object )

It's a cute game. I really liked the art, but the gameplay could be improved. The controls at first are very jarring, but I ended up having some fun with them. They still feels a bit out of place for me, but maybe there could be a way to make them work. Also, most of the timeI feel there is little incentive to kill the enemies, as you have to stay focused on surviving.

Overall, it's a game with potential, and I enjoyed it.

I will join to other comments - not the best controls and cool graphics, but without brushes... The game is great anyway!  

Great work! I really liked the graphics, but this game has a problem with controls.
