nice job! good take on the theme! It's a little hard to see what the visuals are, and enemies seem to take a lot of damage before they die (unless you're on your last heart, so I guess it makes sense). Just would have been nice to have a health bar above the enemies so I knew how much damage I was doing. Also, maybe it would have been cool to add a point system when enemies are killed or some other reason for rewarding killing enemies, otherwise it would be really easy to just jump over them to the end. this has a lot of potential to be expanded on, so good work!
I'd appreciate it if you could play/rate my game as well! :)
