I definitely found the game easy to understand, and I liked that the move speed is quite fast, it means that backtracking through the levels doesn't feel punishing. The movement and camera controls felt quite janky though, I kept moving so far forward I ran straight into the walls. The music got quite repetitive after a while, and some more variety with the environments and enemies for each level would have been nice. Each level ended up feeling quite samey. It would also have been nice to have some more feedback and sfx from the enemies when they get near you or when you hit them.
