I really like your interpretation of the pass it on diversifier.  I think you have a great start to build off of. On think I noticed is there's no way to tell what items still need to be collected when you pass it on. You can't click on dups so when you do and there's no feedback it can appear like you have a bug. I can't wait for you to add a cut scene or even an image of the rats all driving off to enhance the win.

The pass it on / relay mechanic is super creative. The rats are super smooth to control and the movement looks very nice as well. Also having the objects move a little or a lot depending on orientation is a fun way to switch up the basic sokoban gameplay. The sounds were all really well implemented but maybe just a bit too jumbled at times. Like pushing an object out of the maze would cause notes to fall on top of each other. And the rats squeaks could be a bit rapid fire when moving quickly. Very minor complaint though.

Great job on this :)

I really likes the mechanic of other people copying a code and playing the game from there, helping you escape solving the puzzles.

I love the way the rat's move,  so fluid. And the pass-it-on mechanic is so unique. Great job!

A classic sokoban with a ratty twist! Excellent models and animations.
