Good idea, bad execution..
I'll point out a few things first. One, your character is slippery, and even just so much as tapping the key he moves way to far. Two, this game has a lot of potential, the very idea of it is great, I like the idea of it, but you executed it way wrong, especially for a Demo release. Three, you can't design levels symmetrically, like the "trench warfare" map. I'm assuming that was supposed to be all evenly spaced, between the spiked pillars and whatnot, however the last spike is about one "block" away from being centered, and it's way to tedius just for something insignificant in the game (especially a demo). Four, your after you finally get by that, (if you do rather), you have to go down farther, and go through some spikes, then the game prompts you to "check your map for your location and to quicksave." But then there's a huge red thing that flies at you out of nowhere and unannounced. Not to hard to get by. Five, Once you get by that, you have to fall down through a seemingly impossible pit full of surprises on the way down, that you have a little under half a second to respond to before you get shot back up at your checkpoint. However, this is where that Quicksave function would come into play. "So I'll try to quicksave at the bottom" alright, only if the Demo would let you do that, which, it doesn't. Six, slapping random surprises like that around on a screen that shifts from floor to floor, giving you hardly any time to respond to them at all, makes for a very frustrating game. The majority of this game, when going into a new area is Luck that you don't get nailed by some spike wall or giant red space-crab flying at you from the other side, and a smidgen is skill. So, I give it zero stars, because even though the game's idea was in the right mind, doesn't mean it was in the right hands. Good job either way though, maybe you can take those points into some consideration for the full release, if it isn't out yet, that is.
