I'm really sorry about that, maybe you have two joysticks connected at the same time? or two devices trying to move the cursor or try clicking with the right click to lock the cursor. In any case there is a new version of the game that fix a lot of bugs:
This will be the new page of the game with the latest version, in case you want to download it or share a comment, please do it in this new page.
