I think this game could become a really fun experience, though there are things to improve on.
I had issues hitting the enemies and it felt really hard to get past the first encounter, which might be a balancing issue.
I could not get the player character to turn left (might be an issue on my end though).
Maybe add more variety in the levels, as they are too empty and a tutorial (at least a simple UI showing the controls for the game would help a lot).
