i would include the test your might and test your sight but also add .....

...............TEST YOUR HIGHT...............

just like high jump, your player run at the bar and jumps it, but the bar has spikes all over it.

instructions: different colours appear on the screen and you only have a few seconds to press the coresponding button the number of colours shown, the bar hight and the color speed varies with the difficulty.
the amount of times you press the right buttons determines how high you will jump

there will be numbers on the poles that hold the bar to show how high you will jump...
the numbers represent the number of colors/buttons you got correct.

I think a Tag Team mode would be really cool. Maybe allowing you to play through the arcade mode and having VS matches. Of course, there are also some really good ideas on this thread, so it would be really hard to choose.

A survival mode and a team mode like in Tekken 3, or a tag team mode like in Tekken Tag Tournament...
