Remember of Treihadwyl it's a remake from a very old game (1989) named Bloodwych. I do the remake from 8 bits version (amstrad, spectrum, etc). There are another 16 bits version (pc, amiga) but maps, towers, objects, etc are different between us.
The mod is complete, 6 towers with different floors. Obviously original game was simple (and more on 8 bits version) and this mod don't have big puzzles. I put few additions and modifications but the game is the same. There are a lot of upstairs and downstairs. Because this sometimes levels on automap are a little disordered but nothing important for players.
