Okay, so, the good with the bad here. The good is, the game is beautiful and I really like the level layout. An E for effort for the sounds. The glass portions of your walls that you can't pass through need a tiny bit of reflection so you can actually tell the difference between doors and windows or they need to be a different model. The AI was pretty good but the difficulty was WAY too hard. With no aiming reticle it was nearly impossible to shoot anything which would have been okay too if I could look down the aiming sight. I couldn't get the block function to work, maybe that still needs to be implemented. I know this seems like a lot of negative but if I didn't think it had potential, I wouldn't bother. There's a lot to work with here and the game play is pretty good. I would have liked to be able to take my finger off the jump button to control the jumps a little more fluidly though. So far, this is looking really good.
