Yes. But my game has now grass inside houses too so it wouldn't change it to worse. I haven't figured out yet an alternative.
You should definitely find a better DLL to propel your game. This libtcod is castrating your project beyond words . I really wish you were into C# as my help with it would be "unlimited".
My new algorithm for handmade maps allows different types of floors now. I tested it quickly and now I can add lava, floor, grass and water efficiently. Houses in Marwal and ruins of Undershire will have wooden floors in the next release.
The more I program in language other than C# makes me think more how superior C# is. I love C# but however I think my game's been going great with Python, it's more about my skills than libtcod. My rendering code has one more line that allows rendering multiple types of floor at the same time.
