A fun little game, and an interesting concept. With the lack of levels, there wasn't a whole lot to play, but the concepts you have could easily be expanded upon. I wish there was more you could do with the assimilation mechanic, maybe extra abilities for the spacemen you couldn't access in your alien form such as the guns that I can see them holding. Audio restarting after every level/death was a little annoying, but that's not really major. All in all a very solid game, especially for your first project in a new engine. Keep up the good work!
