Nice job ! I can see there is work behind that :) The pixel art is very nice, and the controls are decent. The musics while simple are nice ! But it's not 8-bit / NES style, but I can understand if you couldn't make 8-bit musics. As others pointed out tho, the game is pretty hard but since it's based on chance I can't blame you.
Btw, your HUD reminds me castlevania !
Good job my friend !
