Parkour rats.
Really hard parkour. First time when i test it took me around 2 hours to beat it. Saw one guy beat it under 20 minutes so that let me a little angry :D At end is treasure and on the way u can see fireworks outside the window or switch on/off water etc.

When you play this map you can rly feel how small you are. So possition of mouse which want cheese (which is at fridge) pretty gets u into this role.

Made: WE, block by block
