I'm sorry to hear that! Does the game spit out any sort of error message?

Dang, again sorry about this. Unfortunately this is a bug that a small number of people have encountered. I don't believe my programmer ever found a fix, but if you send me an email (thewhalehusband at gmail) I'll send you a free copy of the game on both Steam and as a standalone download through itch. That way you can get your money back on Steam, then hopefully one day find a computer it runs on. When you get it from itch you can download both a 32 or 64-bit version. Try both - maybe one will work. I do wish there was a guaranteed fix for this, and I'm sorry for the trouble.
