The art is lovely, and the music/sound effects are very high quality. I was immediately sold at just the title screen, it was so slick! I got a bit stuck on level 3 trying to jump over the wall before realizing that you could spam jump to vault over it (I also clipped into the wall in that level). As others have said, the alien move speed is also a bit slow which can make some jumps feel a little clunky. Besides that though, I found the levels to be very fun and each offers a unique challenge using the cloning mechanic. Very fun puzzle platformer!
