Mr. Lumber is a supernaturally powered wood-chopping fiend who holds a powerful grudge against trees of all kinds, and gameplay involves viciously slicing through logs of various shapes and sizes. Even better, Jack Lumber isn't afraid to employ a little harmless punning.
"A tree killed his granny and now he is out for revenge," Owlchemy's description reads. "Meet Jack Lumber, the supernatural lumberjack who hates trees, loves animals, and hates trees. Did we say that twice? The guy really hates trees, and boy does he have an axe to grind."
Don't lie – you laughed.
