Lumber Inc. Offer on RevU offerwall

I’m curious has anybody played this game? The offer was to reach factory level six but I lost track of what level am I on LOL. Because in the game each level has a name but they aren’t numbered per se. I tried to find some information online but wasn’t really successful. I may try YT videos next but I don’t want to spend a whole bunch of time trying to find it if somebody remembers playing this.
