I worked out what was going on quickly enough, and I love the idea of combining the mastermind mechanic with the dungeon crawling I think there could be a really cool almost rogue-lite game in that.
I did really struggle with the enemies though, the angles they came at me from made it really hard to shoot as they would go just above/below my magic and in some cases I’d be unable to jump them because of platforms. Because of that I didn’t get too far, but if i understand the gods hints then I did get at least 2 gems right before giving up.
Controls were a bit floaty but as I’ve noticed from a few games that’s just a personal preference. I also really liked reading about your self imposed 128x128 limit. Those sorts of challenges are a lot of fun!
