Yeah, that all makes sense. The urgency of a game jam will certainly do all that. I've definitely had issues with GB Studio triggers in the past. A done game is always preferable in my eyes.
I'm not sure what I'd personally go for in attempting something like this, but it makes for a fun design exercise. I do find the 1/3/5 approach to be a clever way to approach it.
I'm glad you liked my game!
