I started the jam trying to make something like this, but soon realized it was way more than I could do. You even handed it in early, congrats. It seems quite interesting.
I agree with Iain (Eirreann) below the tools are frustrating at the start, especially for the time that is there. Maybe having each tool being universal but only usable once would be better or if you could pick up and hold multiple tools at the same time?
