The graphics and animations are wonderful, especially for a solo submission on such a short jam! I did find the text a bit hard to read against the background though. I also noticed that levels reloaded before the screen went completely back.
I do feel like there could have been more on the gameplay side of things. As others have said, there wasn't as much strategy as there was "throw the boomerang really hard until all the walls break". I never felt the need to recall the boomerang as it would always eventually bounce back to me.
Excellent work!
