I made simple music game with C2 in two days, for game Jam on Newgrounds.
Playable version, hope you enjoy it:
"Keep the Music", musical game
How to play
Click and drag blue speakers so they remain on-screen.
Speakers grow and slowly fade over time. Clicking shrinks them and prevent fading. Do not let the speakers collide with each other.
Mouse (or touch) control only.
The goal is to keep maximum of speakers playing to the end of track by touching them.
Preloading music take some time on slow connection, wait for "Go" button.
It's aimed at touch control (and, possibly, support multi-touch), but game just crashes on my iPad (have no idea why).
Also, sound operations in C2 does not allow fine control of sound flow. Looks like stable framerate is reqired to play song in sync with visualisation.
I think using midi files instead of multiple waveforms would be nice. (There is no midi support in C2)
Feel free to share your thoughts and post feedback.
