A fun little concept that I thought was well crafted and polished. Could've done with some better explanation on some of the concepts, sometimes there would still be toxic elements left and still some crystals but the level would end and I wouldn't know why. But that sort of thing is common in game jams, I know I'm guilty of it. That certainly didn't stop me enjoying it
Good work, it's a well made game that I hope you're proud of.
