Graphics and sounds are really cute! And love that there was an intro that well done. Game design is also interesting.  Congratulations!

I have one suggestion that could improve the experience: it could be really useful to indicate what the controls are inside the game, instead of having them at the itch.io page. It can be really helpful for players not having to memorise keys.

Love the artwork. Gameplay is pretty simple, but kind of fun. Having the ability to move the system feels somewhat pointless, as I mostly just kept rotating the device, and it worked just fine.

Awesome concept! Liked the simple controls and it was easy to keep playing. 

Nice music and sound effects. 

Could add some more squishy animations for the center character. 

For me it took some time to notice that the 4 hearts are for the bouncy character, and not the center one. UI layout may need some revisions to communicate that.

You could use some pixelated shader / post process to make the game/display area look pixelated. that would look really cool. I've seen some pixelated post process tutorials on YouTube, they might help. 

Overall a fun game.
