Congrats on your game being the reason for why Markiplier played White Knuckle in the first place.
Now people know your game, AND the game that inspired it.
This game is pretty good, tank controls are hard to get used to but it's a nice challenge overall.
I would like to report a potential oversight I think was not intended to happen (simplified so there's no spoilers) : In one of the rooms of level 3 where you get introduced to a new obstacle in the game, the door that's supposed to lock you off from the previous area doesn't have collision, giving you a chance to just walk away. Of course, I still beat it the intended way, but I just wanted to point that out.
