have been playing for quite a bit now, pretty fun and it's got some real nice polish, I managed to get one ingot and two pickaxe blanks, but I don't know what exactly to do with them next, it says the blanks can be made into pickaxes, but there doesn't seem to be a way to reheat it so you can't actually forge it again, also the particle effects used when mining should either not appear at all or appear the entire time, because otherwise it's easy to get confused as to whether you're still mining the ore, I know that happened to me a couple times, at least
You should be able to reheat a blank in the forge with 5x coal by carrying it there and simply continue forging.
If this does not work it must be a bug. It would be amazing if you could record your screen.
In regards to the particles: this only happens on the web version due to performance reasons. I could try incrementing the overall particle count but I don't know how much this will impact performance.
