I had a blast (pun intended) with this game! The visuals are charming and I love a digging game. I thought the possibility for strategic expression here was very cool, though unfortunately the dynamite is OP and becomes the correct action. I think a revised, full version of this game that has more consideration for the action economy, just that I need to choose what and how to dig, would make a spectacular game. I would definitely buy and play such a game.
Side note: the deep underground area is supe cool.
