Great demo, very interesting take on a "entities" game, there is lots of interactions and it was very interesting, the tutorial is very clear and the notes are also very handy, I think there is one area that could see some improvement and is the bullets, there is little room for error and that makes the game kinda hard to enjoy, a little balancing would go a long way since the rest of the game is plenty fun.
The spatial audio works nicely and I think is very well used, granted I did not made it very far into the game...
