I love that you ran with the alliteration of Pickaxe Pete and used alliterations in other names and dialogue. And that you turned the boulders from the original into an enemy with a face.
I leveled my characters up to level 5 and wanted to buy them the best equipment! I got Pickaxe Pete an upgraded pickaxe and a tshirt, but I couldn't put equipment on Larry for some reason.
I also found mashing z to be the best strategy. It's easy to see where there's a lot that could be added, but well done for the limited amount of time we had!
