Hi everybody!
I have some good and bad news.
Good news: I solved the problem of the void assets spawning in the void. At first, I thought it was a Rule Tile problem, but it turned out to be a code issue in my Dungeon Wall Builder script.
Bad news: There’s a new problem :D
It seems that either the Dungeon Wall Builder or the Rule Tile is making the walls disappear when a void tile is placed next to them.
I’ll be working on fixing that, as well as adding new obstacles, fire, and enemies to make the game more playable.
