love the game. gameplay is nice and snappy. the only thing i would change is to increase movement speed but i think thats just a me thing cause a common problem with my game jam games is making everything too fast lol.
It's tough to strike a balance between difficult and fun. I agree that the movement speed is a little on the slow side, though there are certain upgrades which can give you an edge such as the dash, the evolved form and fast form mutations.
