Been playing this game a lot, it's free on the Nintendo eShop (with paid DLC of course). If you have it, you should try this level.

I never heard of it but I should check Youtube for gameplay. I am curious about how a :walrii: level gets played :)
Pretty fun, actually. You have to pull blocks and reach the top.
Ah I see. I'll see if I can try it when my bro isn't too busy with my 3DS.
