Astrocreep is a short point-and-click action game that you can play with your mouse.
A sci-fi horror theme where you play as an alien and help it move through the rooms and build a nest to take over the whole space station.
Start as a simple parasite that grows with each successful kill, and then choose between becoming a telekinetic space octopus or an acid-spitting cosmic squid.
Have fun and good luck!
