Well, as I mentioned on one of my early messages, the entire code and assets for my Encounter game is available on github.
That may only be of limited interest since it’s for a 8bit 6502 based platform, but who knows!
And yes, it’s not yet April 1st but if I don’t do that now I will forget.
It’s not technically “open” source, but it’s available for anyone who want to take a look and eventually get inspired by it, and can be used if credits are given, and as long it’s not somebody who simply republish my game with two changes and make money from it.
