Oh, 30 hours, I can tell, haha. It seems like you were preparing your assets for the theme "Inventory management" instead of "dig it up". I've found several glitches when managing the inventory slots, some power ups disappeared, but besides that it's a game that I would really play again. Feels really polished and fun! You also added a tutorial and highscore. Congratulations!
