The concept is straightforward but it works with the theme!
I think the gameplay would've been better if we were able to determine how much we've achieved. My suggestion would be adding a counter for how many enemies you've defeated and probably adding something to determine the player's health.
Correct me if I'm wrong but it seems the game doesn't have music. It's alright if the game has no music but because of this I'll only be rating Presentation based on your visuals.
Thank you so much for joining the jam and congratulations on your submission!
