Fun concept. I didn't understand the controls though. I managed to merge some notes, but never really understood how. Most of the time they just collided with each other or disappeared outside the game boundaries :(

Very satisfying. I appreciate that the game essentially tells you when it's done, but I kept playing a bit more anyway. It reminds me of typing games, or language learning games, that try to teach you a concept through games. At first I was doing the math in my head but later on I tried to rely solely on my ear because it was faster, which is the whole point of ear training, so nice work!

I love this one. Very cool. I love the logo. If you plan to keep developing this, I would remove the ball movement completely and use something else to show the notes.

Fun game, plus I learned a bit about music theory too! Really glad the chord names appear as you hold orbs next to each other otherwise I'd be totally lost. It was nice going from random dissonant noises to recognisable chords! The level names were very clever and funny, and I like the overall look of the game/logo, and the physics of pushing the orbs together to create chords was nice though it was a bit difficult making individual combinations on levels where there were a lot of notes. Overall the game felt really polished and complete, and the combine aspect really came across well!

I love the concept! I also like the fact that you added the sounds on mouse-over, as illustration. I imagine someone who knows what they're doing might be able to do this by ear alone, which could be a fun challenge mode. However, I have to say that the actual combining of the balls is infuriating. They're always jumping away or absorbing an unwanted extra ball. This game could have done without the physics altogether, in my opinion.

Always room for music games. However, it was a bit hard to play as my notes kept escaping the playarea :)
