Great game! Loved the concept, the gameplay was pretty smooth (though the web-player controls could be better - I'd rather not have to use full-screen mode to avoid the right-click context menu) but otherwise very well done!

The mood was pretty good, atmospheric, dark. The gameplay however is flawed...

The platforming is slidey and difficult to manage. That's what happens when you use the built-in physics for platforming without a lot of experience tweaking it.

The drag and jump attack is very hard to aim - I know it's hard to do a prediction line in native physics but that's what we need for something like this.

The inability to run up and down walls seem weird when you're a facehugger :P

The countdown till the human exploded seems weird. If you're a facehugger that's what you want to happen - you procreate, but in this case it's a lose condition. That's weird, why didn't you just pop off instead of die?

The restart time between deaths is too long when you're playing a one-hit kill thing like this. It gets irritating quick.

The music and graphics are really good, the rest of it are just niggly bits that unfortunately are more important.

I love this type of games and the concept, i like it!

Awesome idea, and the mood/music is really well done!

As Tuism mentions above though, the controls of the platforming is super slidy and awkward. I also felt the dragging attack should have had a much higher lower jump threshold (i.e. you jump much higher, more easier).

That said, making a good feeling physics Unity game is no mean feat, it takes ages to tweak it correctly :).

Slight problems with controls, or maybe I'm not good at such games :D
Other than that, this game is PERFECT!

Nice work guys. The slippery movement when walking was a bit off. I liked your concept, and you had some nice mood going on there.

Very cool game and I love these sounds. Could be adapted to be mobile game.

Too dark, but the idea and gameplay are great!

I agree with Tuism, on basically everything. But I'm also going to add a criticism on level design. The one represented by your second screenshot is incredibly frustrating. You start off basically half a player-length away from instant death. That made the long respawn time even longer since you had to wait for the one guy to turn around before attempting the level again.

I also found it very unclear what the rules were, so to speak. In that same level, I took control of the middle-right guy, dropped off the side and exploded. Do the humans take fall damage? It's possible the bottom guy shot me and I didn't realize it, but it really seemed like I died from impact with the ground. That's the kind of thing we need to know about. In another game, I'd just experiment, but the respawn time made experimentation frustrating. (It was similarly frustrating to learn that you died when the time limit on controlling a human expired...)

Really cool concept, but as a lot of people said, the buggy controls make it hard to enjoy. But the rest is really nice, good job.

Music and animations are fantastic! The controls are pretty difficult to jump around. Really cool game overall!
