Hey thanks for trying out my game! It runs a little slow in HTML5 but it does run -- so it's a nice option for people who don't want to keep anything on their hard drive.
I'm glad you're enjoying the puzzles, I think they're a lot of fun! It's unusual for computer generated puzzles to be so consistently rewarding and interesting to solve, even after what must be thousands of them it still feels like I'm sometimes surprised, confused or have a stroke of insight when playing Monster Mind. It's a really special kind of puzzle!
