Thanks for playing, I know the game didn't turn out great, unfortunately.
As is you can run pretty fast but you're punished for not taking things slow by more easily running into enemies. It shouldn't be too hard other than that, I gave the player what I think is a good amount of health especially in the later levels and kept it hidden hoping to keep things suspenseful, but I get that it's going to just be frustrating for most people.
Thanks again for the feedback.
