I enjoyed the game, but ... in the current version1.6.6 there are unexpected glitches!
I'm not sure if some of the following is normal:
1. A blank penance tile (purple dor) appeared once after a level where Khan's legacy (green) was used in the previous level.
2(a). Since this level, the tiles which the avatar has stepped on started to disappear even though the tiles are not fragile. I checked the 'curses', but I wasn't aware of any curses which would trigger this.
2(b). The icons covered the play area and made it difficult to see completely.
3(a). In this level, there are tiles which could be connected to the existing paths, but the game suddenly stopped and called it over.

3(b). Tiles can still be placed after the game ended, although it had no effect.
4. As other suggested, if would be good if 'curses' could be removed with the 'holy water'. I guess it could be a random one removed or a particular one which the player selects.
