The text for the tutorial is INSANELY hard to read, like genuinely I was squinting and rereading several times. I don't even have dyslexia and I was struggling, anyone who does have dyslexia straight up won't be able to read it at all.
I would really change the font.
The text for the shop is also a bit difficult (again because of the font), and I don't really understand what I'm doing? If I'm selling rocks then I'm not sure why a single big rock sells by clicking for every coin individually?? I don't really get it
I'm also very confused by the "cash out" part, I click the arrows to try and sell(?) the rocks, and click cash out, sometimes it works and other times it makes a little error noise. Also trying to buy batteries I think? And again, error noise.
The tutorial also needs to mention clicking to use batteries you already have
I do like the concept though, the pixel art is really nice and the background is gorgeous!! Just needs to be clearer and more understandable UI & font
