1. enemies are sometimes stuck in the wall (happened few times on the edge of the wall).
2. I have big lags (performance issues, i have integrated graphic card) [the biggest lags in menu i could barely do anything].
3. players character "cheeks" looks weird (when moving left, right or left right bottom).
4.cannot shoot while moving up (the bullet is stuck in the character?!).
5. hard moving on the map (big idle differences, character moving too much up&down, sometimes I thought I would move very close to the wall but it was impossible).
6.sometimes after many failures with buttons and then doing it correctly the character won't give a shot (unknown reason).
7 .enemies behind the wall tried to get through it instead of moving around (you should program it better or spawn them later).
8.no end trigger.
9. when i play the game first times i heard less enemies sound of attack (sometimes didnt hear any).
Thats all :D
