@kamuniaft Thank you for playing as well, indeed we were stressed out until almost the last hour before submission :)
About the things you listed:
1. correct, the ores all do basically do the same thing, they just have different selling values and are for visual variation. A few less would have also done the job, that's true, it was a bit of a hassle to change all of them each in some cases when a change was made as well ;)
2. good to know that you had a bit of a difficulty figuring out the places, we hoped that the custom signs would be enough but we'll keep that in mind in the future!
3. yep, the ore selling wasn't supposed to be like that, but we had no time anymore to reprogram the selling feature again and it ended up being an unintended button meshing ""mechanic"" that can be quite annoying I agree
In the future we will try to have less feature creep and rather 1 or 2 core mechanics that we spend our time on! The artists in our time would also really appreciate that ;)
