I'm sorry about that, information I neglected to put anywhere is that if you use the diamond claws to swipe at the crystals you'll pull them towards you and you won't keep them trapped in a wall.
Thanks so much for the crash report! I'm trying to recreate the bug myself, hopefully we'll get that ironed out before the next update!
Hopefully we'll also iron out the Enemy AI.
We have so many more ideas for the light beam and sound powers, if we continue this project I hope to really expand on that idea in particular.
Thank you so much for the feedback!
