That's good! The little introduction at the start hopefully helped out with figuring out the crystal mechanic. It used to be so much more vague, thankfully I ended up fixing the problems (mostly, there's still hiccups) by the end. The button prompts were definitely a good idea, I thought because it's not exactly a huge game or anything and it's a game jam game so you won't be playing it for long, it just made sense for everything to have prompts.
