At first I was worried it'd be too close to Baba is You, but it's definitely its own thing. Wasn't able to get past the last level, but I think if I sat down for an hour or so I could probably crunch it out.
If you ever expand on this at all, I think having little ghost boxes on the ground showing how each arrow key would move you would be really helpful. It hurt my brain having to keep reading the chart, but I had a great time!
