What a great game, with even better execution! I really liked the art/setting, and the music was solid as well.
We actually made a very similar game, one where you can also shoot at objects to resize them. Our mechanic was a bit simpler due to our team consisting of just two people, and we actually would've wanted to implement the same mechanics of shooting yourself with mirrors, if we'd had more time or coders. I'm very glad to see it in action in a similar game! Well done!
