HELP HELP!! BROKEN IPOD!!!!!!!!!!!!!!?

my ipod touch (2nd gen.) is not turning back on...i was playing an app called LUX Touch, kinda like the board game risk, and then i won (yay!) and then i turned it off to eat then later on when i tried to turn it back on it wouldn't...then i plugged it in to my wall charger and it turned back on and then i turned it off and it won't come back on...even after i plug it in...right now im just going to let it die and see if it will turn on after it dies...i dunno...any help/or advice would be greatly appreciated
