I really love the concept and the aesthetics you got on this one. Everything feels super polished!
I think there is either a bug or an odd design decision I don't get in the mining. I don't really understand the point of making the player wait in real time for the mining to finish. You also penalize the player for being impatient in that if they press the button to move again while mining it eats a turn and gives no benefit. Especially confusing is that initiating the initial hit on a stone doesn't take a turn at all so you can mine one block into a wall, step in the crevice for one turn, and mine all 3 adjacent blocks for 0 turns. As far as I can tell there isn't anything else in the game that is real time, so it was very frustrating to have to wait for the mining portion.
My only other nitpick is with the terminal. It would be really nice to have the players commands be a different color than the rest of the messages to help break up the wall of text and make it more readable. Both of these things are suuuper easy to tweak so I will be rating as if they were implemented or there was a setting to enable them.
The rest of the game is super neat! The combination of traditional roguelike and tower defense I haven't seen done much before, and has a lot of meat to it. The amount you managed to get done in just a week is astonishing. Definitely up there for one of the most interesting games of the jam! Have fun out there!
