The reversal effect was pretty cool, it caught me off guard when I suddenly switched sides haha

This is ripe with potential. Dealing with your previous actions could have a lot of symbolic meaning. After playing a couple rounds, I realized I could manage to stand completely still as the player and kill the boss without getting hit. This made the boss section trivial as the target I had created was very easy. Perhaps if the boss was better at forcing the player to dodge its own attacks, it would make both fights feel much more engaging.

I can definitely see how this idea would be really interesting if fully developed.

A creative idea, although I could figure out how to win, even after reading the instructions multiple times.
