This was great!
I was getting "SteamWorld Dig" meets "Rogue Legacy" vibes from this game.
Not sure how far I got - I got deep enough where the color palette changed - maybe there are a few more levels/ sections to go? I'll give it another go after finishing playing a few other jam games. :D
I also noticed quite a bit of slowdown the longer I played - hopefully it's a quick/ easy fix. :)
It would be cool to have future generations have unique pros/ cons and maybe some tiles that indicate higher quality items/ gold but surrounded by stronger dirt/rock tiles.
Anyways, great work on this - you did an awesome job! :D
