Absolutely love this concept! The animation of the miroorganisms is truly lovely. I like the feel of swimming around in the drop.
I did peronally find the controls unintuitive, I kept wanting A and D to rotate and W and S to be forward and back.
This has huge potential but and even though at the moment there isnt yet a true game as seems no need to eat nor much risk of being eaten but I'd love to see the full game if you keep working on this.
