Yes, there is a "Main map" of levels and random events drop-down on it. There are both levels with enemies and chests with weapons. We need to think about how to get them! :)
Soon my friend will release a tutorial and gameplay trailer!
To get out of the initial cell, you need to find a board, then point at it with the mouse and hold F and pull the mouse towards you (or move the character in different directions) so that the board falls :)
