Foothold, possession action-puzzle game, seeking feedback Thread

Hello! I'm new-ish here, but I just set up the IndieDB page for a game I'm working on in UE4 with some friends. We're looking for feedback, to inform the direction we take from here. Hopefully this is an appropriate place to start such a thread.
It's called Foothold. You play as an invisible alien critter that can possess people and mutate them, and generally cause chaos in a lab environment.
Here's a video we put together:

Also, please check out our site if you have a minute.

Keep in mind this is very much work in progress -- we don't have animations in the game yet, for example. Hopefully the core idea will come across at least! Any feedback on the game itself, or our video, site, etc. would be very helpful. We're excited to start sharing this with people. Thank you!
