The air control is crazy. I can run jump and do a 360 and land back where I started.
The game seems to freeze up for a second or two when the first enemy gets hit by a bullet.
I'm a little confused on whether the enemies are supposed to attack me. They don't try to attack me if I shoot them from far away. The women don't do anything. The men only attack when getting close.
The procedural level generation is cool. Though I did run into a bug where it generated 3 upward ramps that terminated in a wall. I'm not sure if it's just my luck, but if I take the right hand path, it almost always leads me to the target.
The skill tree needs some description of what the upgrades do. I figured out the bullet one is how many bullets you get in a magazine, but the others I have no idea what they do.
Sound is alright. The music sounds good, but the gunshot seems to not be piercing enough for the enclosed space.
Gun feels ok. Bullets should probably be faster.
I like the idea of examining people's masks to determine who should be killed and I think that should have been more of a focus compared to the shooter mechanics. Toward more of a object recognition or assassination game rather than an action game type.
Overall looks like the start of a game. Not too much here yet, but I could see it developing into something fun.
