Solid little platforming game! I was quite confused on what to do at first, because I don't know what to drag. I thought it was the colorful little blocks lol. Until I realized that there are two blocks at the bottom left. I think it would be good if the bricks that can be moved is in different color / size / pattern, so that it is more easy to be located by new players. Grid lines to help placing the block exactly on where would also help.
But after learning the mechanic, I played more levels and it is very enjoyable to walk through! Thank you for the game. :)
