Today i played the v1.01 a bit more extensively and noticed, that from level 3 onwards, three of the four ghosts are permanently broken in their graphical representation. They are yellow with stripes inside then. And in level 2, in one of my games today, a ghost walked around outside the labyrinth for a short time, before he came back then. There's probably some more broken in this concept version, but it was pointed out before in the infos, that there can be such kinds of problems with the ghosts, because it's just a concept version. But I have to say, that a full version of the game with this labyrinth here, would also be interesting. It's a bit harder than the normal one and I also like the idea, with these corridors, that have no exit and in which you have to turn around.
