Thank you for your feedback (+1 for mobile, noted)! :)
Oh, I remember the "tank controls", but until now I had no idea it has a name... :D
The lights and shadows are need more tweaking as well, it's not how I imagine to be, but that happens when you have deadlines.
Fire rate. Yep, it was planned as well, and a shotgun too. You could switch between them with a [LMB] swipe up or down. But the game was too short for more than one gun, and somehow I ended up with the simplest one, e.g. no reload, no fire rate limit, no fixed amount of ammo. But again, these will be all back once I continue to work on this project.
The zombies... yes you can see them, I don't have an excuse for that, it's just bad game design. :P
