As others mentioned, I also suffered from delayed mouse clicks and keyboard inputs. Simply downloading DDrawCompat (a DLL file) and placing it into the install folder solved all of the issues. Game ran fine afterwards. It's an odd, quirky game and I really enjoyed my time with it (though I didn't do well loll). There is a mini-tutorial that kick starts you but you're mostly left to figure it out on your own. It can be slow at times, though I feel like it only really slows down when you make an absolute disaster of your business. I got this on sale for $0.89 AUD, and I can't really complain at all. I love these older, weird games and this fits the bill perfectly.
