what are you talking about? The game was tested on a normal computer keyboard, and it works as usual. Unless you have some kind of "special" keyboard, which is different from normal computer keyboard.
I haven't played this in a while, but I believe it was the arrow keys that were the issue. Sorry if I seemed like I just wanted to cause a ruckus. My keyboard doesn't have arrow keys and my wasd weren't working ingame.
I just replayed the game and I understand the problem. The game required arrow keys to move the crane up and down, but uses wasd to go back and forth. A simple fix would be to allow to change keybinds (I'm not a dev I'm not actually sure how easy/hard that is).
