Nice puzzle game! The graphics and audio create complement each other well. The mechanics are simple yet leave room for variety. Was stuck on level 2.4 for a while.
I like how the game teaches the mechanics, first forcing you to walk over basket, and later showing you can put smaller animals in bigger baskets despite the different shape.
Would be nice if you could see which level you're at. An undo button would be great. And the ability to restart and use the menus without using the mouse since you don't use the mouse the play the game.
