yeah I definitely understand the feeling of not knowing whether I want to join a jam or not. Whenever I do solo jams, it's always a crap shoot on whether I'll submit since unlike team jams, I'm not letting anyone down if I decide to not do it.
Ah yeah I seem to have the opposite issue with globals, I feel like I overly rely on them which means I can't trace what's breaking my game since it's all just a bunch of signals. It's one of those gray middle ground situations and I wish there was just a right answer
