Thanks a lot for playing! That developer option is probably the hardest part of everything, it stops if you manage to get your cursor on it but maybe I made it a bit too fast !
Ah, that isn't part of the plan at all, I completely forgot to test the exit button on the build before releasing, something might be wrong with the way I exit the game :/ I'll try to fix it and submit an update after the voting period is over, thanks for flaggin it!
