I like the sokoban quite a bit. The tile countdown was such a simple yet deep take on the theme, definitely a strong contender for most elegant take on the theme in terms of mechanics. I also liked the art style, everything was smooth.
My only request would be an undo button. So many times I found the solution then misclicked and had to start over, sometimes I forgot again. Definitely my fault, but undo button would be #1 pick for update.
