Oh they have some nice names! Would love that bit of lore on one of those stickers!
Fought a lot of Grey Matters and they are cool. By the way, I've remembered one thing - there looks to be movement queue for dodging puzzles and it kind of double edged sword especially on skelies - you can press button and move 2 tiles in it, passing the safe spots. It felt a bit sensitive to jump several spaces so even if i tap the button - it would still sometimes move more than one tile. Maybe something to do with frame rate affecting it.
