It's a really enjoyable game to play. At first, I wondered, if the game was going to be as sluggish as it was at the beginning, but that was of course before you get the power suit. Once you get that, there's a very nice flow to the gameplay. Not only you get different features introduced nicely along the way, but the story is also advanced well between and during the levels.
I'd like to invite this game to our Game Development World Championship!
