Super cool guys! We both had similar ideas lol.
The art is really nice, especially the title logo. I liked the progression system, and the enemy designs were cool. I wish the hitboxes for the enemies were a little smaller, and it was not always clear how much damage an enemy would do, causing me to die when I didn't expect to which was a little frustrating, but those are nitpicks.
I thought the core gameplay worked super well. Also the audio was great. Good job!
