Thank your for playing and the throughout review. Your are right with your points, I need a minimap, maybe some tutorial screens and the balancing was way of.
I ran out of time at the end, as I was focusing to hard on the engine and fixing all the bugs, the verticality brought with it.
I see now, that the standard for movement is like you described here. I was coming from a DOS era Doom point of view, were turing would be on Left/Right or A and D, but as I played so many entries now, I feel that turning with Q and E actually is the better way of doing things.
