I'll be honest, I think this is way too complicated of a game to give to players in a game jam setting. It's the sort of game that really needs multiple levels of gradually increasing difficulty and a slower introduction of new systems. I found it too overwhelming at first glance... over a dozen action words / concepts that I didn't understand yet, everywhere I looked. I didn't really know where to start... the Basics in Help were not basic enough! Starting with the first sentence - "consume every rival fungus" - I don't even know which colour fungus is me and which is the rival. As developers, we underestimate what new players know (I get it, I've also made games that unintentionally confuse new players at first).
I don't mean to rag on your game - I bet there are some great concepts and strategic systems in there! But unfortunately hidden behind a bit of an impenetrable layer for my brain to get to grips with.
