This was such a clean game. The colors and the glow just felt relaxing and almost soothing in a weird way. I was actually playing this with someone else in the room who said "what is that? I love that sound!" and i can't agree more the sound of collecting a blob is super satisfying so perfect choice there. normally I'd suggest adding background music or something but in this case, with just the blob collecting sounds it felt perfect.
Things I'll note, the game is sort of luck based. Since the blobs randomly drop from different positions, sometimes it is literally impossible to collect them. A few of those in a row and you can easily get screwed. Although I like the simplicity and relaxing nature of the game as it is, I feel obligated to ask for more stuff to make it feel more unique - like special blobs that make your paddle faster or wider or increase your "health bar" at the bottom. Just something to add to the gameplay. However, take that with a pinch of salt, I think it would detract from the chilled out vibe this game you were going for.
Great job!
