After a ton of problems, I have finally started work on a version of Doodle Jump for the Intellivision using INTY Basic. Right now it's just a square jumping up but I want to change it to a creature of some sort. I have one in mind. I also am going to add a 2-player version where the object is to make the other player go off the screen downwards. As well as sound and other stuff.
Let me know what you think or if you run into any bugs or something.
