Well...Frist of all: What a nice graphic appeal! The music, desing and art are just in the right place, doing the right stuff, Great job!
Now, about the game itself... It is not bad, but some mechanics make it harder than it should, I guess...
Take megaman as an exemple, its a freaking hard game! But isn't unfair or frustating, it's just hard as f#c$ and the player need to deal with that. Ice Story is in the right direction to be that kind of game, but needs some ''polish'' in the gameplay to give the player that addiction of trying just one more time.
Anyway, it IS a game full of potential! With a little change here and there... I'm sure that I will be giving it the last stars soon, Good Luck!
