Music Galaxy is a proof of concept map; it simulates a piano keyboard. When the map initializes, 53 Engineer Bays are spawned and arranged like keys on a piano. Players simply left-click any Engineer Bay and a note will play. All 53 piano sound clips were digitally recorded and imported onto the map (thank you DrHu). Up to 6 players can play together. The map is published on ALL battle.net regions. The video below is a live demonstration of Music Galaxy. Can you guess each song played in the video?
Just throwing some ideas after watching the videos... It would be nice to have some kind of a metronome, to make sure people keep in rhythm. Of course it could be a problem with the lag, but overall it should help keeping in sync with other people. I guess only the host should have access to this function, like a tiny window displaying BPMs, allowing to set them higher or lower, and mute/unmute it. There should be something on the UI as well to let everyone know when the tick is going to happen.
Maybe you should also allow players to use their actual keyboard to play tunes, instead of mouse clicks on units. There is a problem (again) because layouts differ from a country to another, but maybe it can be fixed by allowing players to pick their layout in the lobby (if the setting is not set to default for someone, just apply the differences instead of applying an entire preset each time). It will be easier to play fast tunes if you remove the risk of missing your clicks.
