Gang, This is legitimately so impressive. Loved the way it looks and sounds, An incredibly unique idea with a nice introduction of new mechanics as the game progresses.
The only issue for me was the difficulty/tedium in reselecting blocks that were already placed down, but i don't know how i'd have approached changing that, so *shrug*
It is evident that a great amount of work and effort has gone into this, you should both be proud, cos i think it looks/sounds/plays siiiick!
