Really nice visuals and the music and sound effects fit together well too.
It took me a few attempts to understand how it all works, and I found for my screen at least that it could have started zoomed out a little bit more, especially as the scroll speed is a bit too slow and you have to get very close to the edges to scroll (that was awkward on a multi-screen setup as I kept leaving the game screen. Maybe add in arrow keys for scrolling as well?). Once I understood what I needed to do, it was pretty fun.
It would be helpful to have a bit more time available at the start of each game, to get a sense of which mines were where, and a couple more sound effects to help note when ovens finish and new materials are available.
Thanks for a fun game :)
