The rules of the game are a bit inconsistent. I can recover an alloy plate with dig leverage and chop, despite not having the chop skill yet. Would make more sense if you actually needed them all.
Also after 10 minutes I still have nothing to craft. Maybe add an item to the craft list from the start so I have something to work towards. At the moment I'm just clicking stuff waiting for progression.
Regardless a fun and original concept, well done. Will keep playing to see if there's any other mechanics to find.
Edit: I'd like to add that you could easily spice up the skills by making them more descriptive. For instance, map the "large" item property to a "Haul large items" skill instead of just calling the skill large as well.
