Ah so glad you enjoyed it, and those are some awesome suggestions! The crystals that shoot bullets are meant to be smashed with the cane - they take huge chunks of her health away if you do that, and getting to them forces you to use the grav-switching ability. But I think most people aren't figuring out you can do that! I'll definitely tweak and add more stages if ever I return to the game, but for now I kinda want to move on to the next project :P
