Really cool concept and overall a great entry. I just couldn't solve the level pictured below. I think this is the intended path, but I can't figure out how to wait one turn at the start. It doesn't seem possible with the available keys.
Thanks for the feedback!

You’re right about it being the intended path. You can use your E to wait at the start, then hold the E you picked up to open both gates at the end.
