Neat game. I included it in my compilation video series of the Ludum dare 42 compilation video series, if you’d like to take a look :)

I like the minimalist visuals, and the progressive music concept. However, that last part needs some work, because as it is, it's not really pleasant to hear. Plain sine wave just sounds like a phone dial! One suggestion I could make is experimenting with stretched sounds and slowly changing effects (such as bass filter or additional instruments). It's a nice way to compose with sustained notes, yet making them evolve so that the music feels flowing.

Still an interesting concept, very accessible and with potential. Good job!

Nice idea, but the audio was incredibly jarring, and trying to map orthogonal controls onto diagonal directions is hugely irritating as a control scheme.

I know the game is called chords but listening to sine waves meshing can be a little jarring. Perhaps they could be parts of jingle or short musical sequence? Either way the audio lends very little to the game. Its mostly a puzzle game where you collect items (in this case, notes) to complete the level. Perhaps using w,a,s and d to determine direction and making the block auto-move to the beat of the music? The controls made sense but doing it manually took too long. The game has potential but it's still pretty rough in design.

It needs some improvement.

Because it's not fun to play, and painful to hear...

Hey! I like the concept of the game (I'm a bit of a sucker for puzzle games). I thought the final level with the timing challenges was a nice start, and I was looking forward to more puzzles from you:). The main comment I have on the game as it currently stands is that long tones over an extended time can be quite grating. Even if you added in just some variation like beats it could help break up the monotony of just the chord tones. Good luck developing!

Hey! I just wanted to let you know that a video of one of my playthrough/reviews is up and you're a part of it!
