Very fun game. The only one that I got right on my own was the first one. Mainly because there was hints to the issue in the error dialouge. It probably would be a good idea to give hints in the error dialouge. It's also realistic because the error usually guides the programmer to where the issue of the problem is. Thats the one major critique I have. Also why did you torture yourself, I couldnt rate you on simplicity lol.
Anyway this game is amazing. The OS screen and movement felt good. The sounds were great. And it felt really great! 10/10
