Is it normal that bullets go through walls? They fade away and it's hard to tell when they stop hurting.
It didn't bother in the 1st levels, but later there's not a spot I can try regain some HP. This added to the fact that most paths, on later levels, are made in a way you can't get through without being hit = insta death. +As I'm hit while being respawn... move or not, it's just impossible.
...and the movements were a bit weird, like on the ladders where at a certain height, you can't climb higher (probably because not part of the maze-path?) + jumping was sometimes stiff.
But overall I really like the idea, the HP system with the maze-like style path.
Reworked, this could be a great game! :)
