That crank mechanic and design was the first design came up on my mind for my game, then had to change it according to more mining theme and funny dwarf topdown :D
I feel lack of music but audio completes and gives dopamine through the game IMO. Very addicting, a bit finger tiring (loved optional way to spin crank btw) but so fun!
I have a personal campaign of finding more fun Spincremental games (clicker and incremental genre) and highlighting them) helping me discovering new gems in this post, and I have added your game to that Spincremental Collection. I would also appreciate if you suggest your discovery about this genre by reply to this or comment on this post!
