Whatawalk! silly walking with wobbly legs is a highly addictive classical game, similar to a bubble burst game. Even if you've never come across it before, playing it just once will get you hooked.
Instructions:
Pull back and release to launch your silly, floppy legs. Walk across short and wide gaps. Just be careful you don't fall in the water!
Hit the flags to get a checkpoint. Keep going and see what level you can make it to.
