As someone who is fascinated by Boids, I am glad that this exists. The visuals are clean and the choice of music makes for a nice atmosphere. For criticism I agree with some of the other comments, steering is slower than I'd like and when you have a bunch of heated FLOWs flying around you it can be very hard to make out your character from all of them.
On a side note: it can be a bit tricky to get the FLOWs into the doors sometimes, I wasn't sure if it was because they didn't have enough heat or too much of it. Could've just been bad luck that my last FLOW kept dodging the door.
