I have no idea why I merged 682 of your little bubbles, but I did. Congrats on submitting your game!
This was surprisingly pleasant. The music didn't feel repetitive, the gentle atmosphere was great. And the control scheme was really novel. Just pushing things with the mouse isn't very common. The bubbles felt very light and floaty and just about right.
In the later stages, a large bubble feels a lot less bubble-like. It doesn't seem to float with the same weight as smaller bubbles. And the SFX for colliding with the edge of the screen could have been more bubble-like.
I don't really know what else to say. It's a very chill experience. It's not quite a game, but I quite liked my time with it. Well done! Keep making games!
