This is very fun and relaxing, I like the music too! If you're still looking for feedback I have a few points:
1.) when collecting a lot of the orbs I found the sound effect to be a bit too loud compared to the music (so I didn't want to turn the volume down)
2.) Have you experimented with giving the other blocks the trailing effect that the small blue ones have? I thought it was noticeable that the other ones didn't seem to have it so I just thought Id mention
3.) The giant pink parallelogram just kind of pops in. It might be nice to give it a pink spawning glow effect like when the other block waves spawn in (or something like that)
Other than that I though it was great, nice work!
