I stumbled upon The Linux Game Jam 2017 just in time to enter it the day it was starting. It gave me a really good excuse to work on a game that I had been wanting to start for a couple years now. The only real requirement for the Jam was it had to run on linux. Browser, JVM, Native, etc. As long as you could start it without using Wine. I chose to develop my game in Pascal using the ZenGL library to get some basic stuff out of the way.
