I have all 3 games but the first one doesn't work. It says something about full color. I don't understand this. 2 and 3 work fine although 3 has breaks in the music. I really want to play these in order. What can I do? I hope you understand this because I can't.

Hi, I've moved your post over to Glitches because this sounds like a technical problem.

Please provide more information: is this an error message that you get when you try to run the game? And if so, it would be very helpful if you could write down the exact words of the error message that you get.

Plus what operating system you are using... XP, Window 7, Windows 10???

I'm using Windows 10, plus it says full color not main color. 2 and 3 start fine just not the first

There is a suggestion here
