The Very organized thief

[B͛ᴚ͛Λ͛N͛Σ ͛SH͛♢⊥͛]

I know that this game isn't on Steam, but If anyone knows how to solve my issue, I'd be glad. So, my Very Organized Thief game won't start when I press space. It was just playing and working the day before, but now it doesn't react to my keys. PLEASE HELP!!!
