You can mine anything but the black dungeon rock by right clicking. There is a fighting and a building mode switchable with TAB.
You don't need any tools for crafting, I must have messed the recipe up somehow. Anyway, in this version you can give yourself items in the top right corner with open inventory, I will post recipes and item ids in case you want to explore a little.
Craftable items:
All items in game(apart from block that can't be put into inventory). If you want to add some to your inventory, the ids are: column number*1000+element number, so Double wooden dagger is 0, Cloth shirt is 1001..
