Could do with a difficulty setting that includes when you inherit someone else's log pile, someone who really enjoyed making every cut on a new and more inventive angle than the last.

Normally a wedge is used to split the wood, but it also doubles as a wedge to be wedged underneath just so you can get the log to stand up.

Also, Y sections (ycombinator mode?). 40 hits later and you might have a nice pile of woodchips, very rarely will it actually split in any clean way.
