Interesting idea. Problem is, at first i didnt know what to do(took me 2 levels to understand), and most of the level you are just sitting there doing nothing, you cant even actively stop the boomerang if you want, it will just bounce and continue going like before…

I think this game has a lot of potential. It ended up being a little frustrating, maybe respawning without the text but also maybe being invulnerable while you slide if the boomerang is red would make you feel less helpless. It's definitely fun at times, but could be a lot more fun with some mechanic tweaking and polish!

Very neat mechanic, although I feel like it could have easily been a ball, there's a missed opportunity with the way boomerang move. Maybe you could have levels without walls?

A few UI issues: your text appears above the level, it's frustrating to not see a part of it after you through the boomerang. Also, the transition after you lose text way too much, I just want to skip it to start playing again. Having the boomerang indicate that he's about to change it's state could make a huge difference in terms of readability and perceived fairness.

Good luck!
