Thanks for playing, Andrzej.
Yeah, stretched a bit too thin, but these thing are remnants of the tool I used. I am not a programmer and wanted to focus on the storytelling and worldbuilding. I simply had no time to eliminate them from the game. But I know that this will hit me in the "theme" rating.
Would be nice to know more of your guys thinking at the start of the game, so I know what confused you. As for the "movement" issues. That IS a dungeon crawler style of movement :) Try out both "Legend of Grimrock" games some time. Or The Bard's Tale trilogy on Steam.
I am working on this type of game in my spare time and wanted to bash out something small with this gamejam to boost my motivations for it.
