Kind of weird, i loved the idea but, id be cool if you see some progress with the shape. But more important... there's a glitch in where i went from 320 to 2780 and it got impossible to keep on playing.
Glitches are the first thing you should check in a game developement!

I too got the glitch. It jumped to 3550.

I get this was done quickly, and 3D graphics arent easy, but this was too simple. Basically just playing simon says, with increasing speed over time. When I reached 500 it glitched and went straight to 1990, and the sequence would fly by so fast I barely had time to see it, so that was basically the end of the game for me. Just tapping in a sequence in silence with some panting noise isnt that appealing, go figure.

So instead of getting fit you created a game about getting fit for people who want to get fit to play instead of getting fit? I like your sense of irony thats what's earning you points. As for the game itself I'm biased because I dont really like those guitarhero things. Also the keys came so incredibly fast after the treadmill it was impossible to play. Maybe it was a bug though because I jumped from 80 to 1340 points.

Boring, and unrewarding. Unless you are making a point about actual weight loss, you get low score.
