I had a go at Tower Of Dread. Using DSB 0.61 ( it was developped using DSB 0.60 ).
I found minor issues. A stair up that has no side right wall, the rendering looks wrong. You don' t see creatures that can attack you while going up and you cannot fight back.
A similar issue with a door and its door frame with no wall on a side, this seems intentional, the door works but the rendering is odd. When you are in the door, you do see a wall and the door frame on one side, on the other side you don' t see the door frame. There is more wrong at this door because of the missing wall.
Another stair up with no side wall on either side is extremely confusing, odd things happen when going up and down or sideways.
Well, stairs and doors do need walls on both sides.
Game over
