Thanks for the detailed write up! I am honored that so many people bothered to stick around and 100% it.
I was re-tooling how the pickaxe functions in combat well past the halfway point of the jam. To be honest, I was never quite happy with it. I think the wall jumping is clever but it's definitely missing something. I think I had a design breakthrough 2 days after I submitted the game (of course) and I will definitely be re-working it if this gets further development (and it may).
I was not aware of the functionality provided by these templates or that jams tend to allow this, definitely useful to know for the future. I'm pretty opinionated, though, so I will probably just end up making my own. Thanks again!
