First off sorry for the late response, I have been exceptionally busy recently. Thank you for the post. There is nothing wrong with the game technically.

I don't have the different variations of the mines separated so it doesn't prevent the ice mine from being used at the ore mine. That will be something I fix as I work on more of the game's generator. It was never designed to do what I'm making it do.

The design in your screenshot uses hologram blocks that have no collision. I'm probably going to modify the design to change them to a collidable block which should also reduce the glow a bit.

I am tracking this and it is on my to-do-list of things to fix. Thank you for asking about this and keep asking these questions it helps me out a lot.

Hey there! Thanks for your reply! I am really looking forward to the next version! Thanks for all your effort!

I thought it was not unknown to me! ^^
