Acorn Arcade Review Santa Cool is a pet project of mine which I started a long time ago and haven't really done much on since. The idea was for it to be a PD game for the RiscPC that could be released around Christmas time, for obvious reasons. I can't even pretend that I can program and the coding is very bad basic, but I feel that it could be a very playable public domain platformer. I have spent a lot of time creating all the pre-rendered graphics in 3D and the result is a set of high quality graphics.
