I have been working on a full game for a while my the person I'm working with left the country for a couple of weeks so that slowed down. I also have been watching GMTK for years now and have always wanted to join one of the GMTK Jams before but have never done it until now.
I made my game a puzzle platformer called Broken Robot where you can only press each direction once per stage. The making of the mechanics took by far the most time for me, to make sure that everything worked well.
