Okay, since this jam is about improving, I'll not tell you about the current state of the game, only how to improve it:
- Smaller screen, doesn't fit on my laptop
- Less numbers and less things in general - stone, depths, some gems, some warehouses etc. I would like it more if there were less things, but those things were more interesting
- More places to click. Right now it's only stone at the left and stone collected in my machine
- Font is too small and hard to read
- More interesting short-term goals, to add more interest to play - what am I playing for? I personally played to see those cool bulldoser animations from the game page. I haven't seen them
