One screen puzzle

I feel that I can't rate this fairly so I won't. I'm not entirely sure of how I'm meant to be giving my answers. I tried typing the numbers in, I tried WASD, and neither did anything visible. I can't tell whether or not my answer was even registered. Although I could hit enter to make the number next to the timer go up. That was cool.

Simple, yet amusing! nice one

@yokcos click on task, WASD is for map moving.
@Aden Manson thank you.

Simple concept which is interesting. Can be improved. Well done ++

very confusing interface but i managed to get some exercises solved...not that much fun though :(

When I opened it said: found a serious problem...

@Vladik Plays what OS do you use and is it 32x or 64x?

Math... my worst enemy

nice work
