Love the game, but the level editor is glitched, every time i press esc on my keyboard to get out of testing or load up a saved level, the game crashes and stops responding (this if for the newest version btw, 2.1.4 old engine)
could you possibly try reinstalling the game? this doesnt seem to be a bug for anyone else.
I did about two times, I haven't played it in a few i'll retry it and get back to you.
