Have you tried talking to Helpscreen or pressing W/A/S/D?
About the key bindings, I'd be honest with this, not sure if this is a problem or if it's normal, but when I click the "Controls" button, I get this...q
Nothing appears, just a black line with a "DONE" button attached to it.
This happened with the alpha 0.0.9 of the game and I got the same "Player not moving" problem. I got the new version just today and this problem continued. I don't even know...
Noooooo I'm talking about the files at C:\Users\PUTYOURNAMEINHERE\AppData. I forgot whether Local, LocalLow or Roaming has it but there should be a folder called "STROBOVSKY" in there. I meant try the save data, not exactly the game data.
Look, I got my achievements corrupted and they were all big red Windows error signs. Maybe your save files are corrupted as well.
