Raised crypt is finished. DOWNLOAD in my google drive folder (raised_crypt.zip)
Example image:
Notes: this work currently consist of 8 extra tiles (3 raised corridor tiles, 4 tiles for the raised wall and one new edge tile). So far only corridor is possible to be painted on the sloping terrain as I don't think it would looked well if there would be anything else such as corridor-end tile (got some ideas how to improve this, but I guess nothing I could finish this month, but maybe later). Models are not compiled neither put into hak yet - the zip is basically copy of my working folder. This addition is made on vanilla crypt version, if you use the diagonal walls you need to merge it (Possibly I can do the diagonall walls version if you wish). And as I said already, toggle Fade geometry in the toolset to get rid of the grid - its purpose is only to help to build the raised terrain, its not visible in game (texture comes from Sen's Mines and Caves tileset but its included within files so it works standalone).
Im still working on the raised dungeon, not sure if its even in the scope of this challenge, if not I will release it standalone.
I playtested it very thoroughly, but if you find any issues let me know.
