Pretty solid overall! The game is pretty much just the best part of mario galaxy (i.e. the shadow clone guys)
The only suggestions for me to make are nitpicks or QoL changes. The enemy hitbox feels a little too large. Making it smaller than their body would give the player more "near miss" moments.
a "next level" button would be nice. several times i forgot what level i was on LOL.
The hover orbs could've done with a visual indicator of when you're close to them.
