Ah drat XD I completed all 100 puzzles on web browser onto to then realize that was still the "demo", so I'll have to replay them all (my brain just assumed it would be the full game since I own it lol). My silly mistake aside, this is a very very fun puzzle game. Things were challenging but never to the point where I was frustrated or took me more than a couple of minutes, making it the perfect brain break between homework assignments. I highly recommend even just playing the 100 demo levels if you can, but the $3 is well worth it.
