The visuals and sounds were really pleasant. Also liked the subtle animations, it really makes the game feel better and alive :)
I needed 1-2 minutes to figure out what I needed to do, even after reading the game rules. If it was more intuitive it would be so much better, nobody likes to read game rules :) . Although due to the unique gameplay it would be quite a challenge to make it more intuitive.
PS: Also consider building for WebGL on jams :P
