Originally, I incorporated the game features into treasure chests because I wanted the player to feel like they had a buy-in with the tutorial, rather than being given directions. I'm still learning how to make tutorials; a few game jams ago, I wasn't doing them at all... oops.
I was curious how it'd be received if I treasure-chested the game features, especially since I didn't have plans for other items to put in treasure chests (but I love treasures so much!). I was expecting it to go either way.
I made the ball-buster after finding a couple dozen places where I was stuck behind balls. Definitely need to get better at level design... >_>
Thank you for the kind and constructive words!
