Thanks for the feedback!
On my machine it seems to work fine, however there are a couple of reasons i can think of that would cause it to not work:
- Maybe you didn't know you had to collect (using the collector block) metals, this would mean i need to add a tutorial soon (or at least a temporary one)
- This is what i think is most likely, the metals look really similar right now. And you might have mistaken copper for bronze or something like that. Which means i should really add in names to each resource (i don't know why i didn't do that in the first place actually) and i should probably also make the sprites more distinct.
- There might actually be bug that doesn't happen on my machine. In which case i don't really know whats going on and i can only hope it happens on my laptop so i can get some information on it.
I actually just implemented the number keys as block selection keys. So that's coming in the next update.
I was planning on doing this, but at the moment i can only make them even slower than they already are and make them upgradable to their current form. However i can slow everything else down as well as the conveyors and speed the game up and it would probably work. I haven't tested this yet so i'm not gonna promise anything.
