At first I was not sure how to play. I thought arrows are using to pass objects instantly left or right.
After some time I discovere space is for grabbing.
I liked the gameplay, it's simple yet satisfying, with the need to concetrate for a moment to get where to pass object.
Art is good, very dynamic and alive. Also interactivity of screen and music is very nice. Loosing made me uneasy in a good way for a game.
