So glad to hear you had a good time :) . Sorry I didn't make it clear you can overlap multiple characters in the tutorial text. I'll have to revise that language in the next update. Originally I wanted to have rotation buttons but couldn't figure out a good way of implementing them that would also work on mobile. I figured being able to push them against the sides of the play field to rotate was good enough for v1. I'll have to think about how to implement rotation controls for the next update. Thanks again for playing!
