Thanks! Yeah, wish I'd known about grid-locked movement back then :)
I came back to this game and got through the rest of the story mode. I'm really impressed with the game's variety! The game definitely picked up towards the end for me, and I enjoyed the tougher puzzles and last two bosses especially. It's really nice to see all of the extras; it's clear that this game was a real passion project. I definitely want to start checking out your other games after playing this!
