Cool game! I managed to get to wave 43 or something after a couple tries, forgot the score though. I like sound effects, and the background art is very beautiful. I do have to say it is extremely loud hahaha, but that's fixable. Also the game feels smooth in terms of movement and animation when moving right and left. Idk why but it was satisfying to play. I tried to use the cheat code by pressing the 4 letters at the same time but i'm not sure I did it correctly.
Cool concept. Keep up the good work!
