This is really awesome! Had a lot of fun! Of course, very little to explore, but I felt totally like wanting to explore more. If you would add darkness, torches, different bombs, different dig sites (so you know before digging what "quality" you can expect) et cetera then this could become a really really good game!
Thanks for the feedback and ideas for improvement!
Because this was a game jam entry I could not implement everything that I had planned. Torches / darkness and fast travel were definitely on the list.
So far the feedback has been very positive, so I am considering to turn this into a full game. Any further feedback is always welcome :)
