You're very welcome! I haven’t actually rated your game yet — I usually wait until a jam finishes so everyone has a fair chance to update or polish their entries. I just checked it out of curiosity to see how others responded and how your game might evolve.
Honestly, I think it’s been rated a bit harshly — it’s clean and intuitive, which is exactly what you want in a puzzle game. I really like that you can unlock levels, too. If I could suggest one thing, it would be to add a bit more satisfying feedback when the balls successfully meet — like having them merge into a larger ball with a new colour created from the two originals. It would give players that little “yes!” moment and might make the wins feel more rewarding.
Wishing you the best with it!
