Arrow keys or WASD to move Down key or S to : Go down the wooden platforms. Take a box. Fall faster. Jump less high (Yes, it's possible) Space to switch between the cat and the dog. R to restart the level All levels are possibles. If laggy, try Turbowarp : turbowarp.org/698083091?fps=60&interpolate&clones=Infinity If you use Turbowarp, ACTIVATE infinite clones (else it will probably bug...)

Lot of love Levels solutions : Level 1 : Just go to the green portal. Level 2 : Use the trampoline to reach the wooden platform and go right. Then, use S or down key to get down (and go to the portal) Level 3 : Go in the hole at the right of the arrow, press [space] to switch your character, go to the bounce pad and jump over the wall. You can now collect the key. You just have to jump on the box, and then in the portal. Level 4 : Go with the cat and the dog on the wooden platforms, then go left. Get down; right, and up. Climb the stairs. Grab the boxes, and climb the wall by stucking it in the wall. If you get stuck, go down the wood platform and go up again. Then go in the left hole. Level 5 : With the Dog, go on the Cat's platform, jump on he, and go pick up the key. Level 6 : Just go in the hole and wait a while... (You can press S or down key and put in turbo mode.) Level 7 : With the Cat, climb the two (invisible) stairs. Level 8 : Don't walk on the blocks over the hole, use invisible blocks.
