Hey! Your game has a quite unique idea and is fun to play. Showing your time in the end is a nice addition to give the player a reason to replay the levels and get better times. Although I'm a little worried about the pieces getting stuck in the corner, so far I was able to get them out by just throwing the body into them.
What the game lacks most is in terms of style. Changing the background and walls, adding a background music and a sound effect for snapping the pieces would go a long way to improve the game. Also, the end screen and the hint popup could use some polish.
Overall, this game has a nice and original gameplay, but needs some polish in visuals and audio.
