Thank for the long review!
About the theme: I first started with a dungeon crawler where you move the dungeon (the map) and the player stays in a fixed position but it lacked something, so I just create a spherical dungeon instead of a flat one and choose to move it with the table. So you move the "world" and the player is in a fixed position.
Yep you did it well, it's a game about control and not rolling fast, but if it takes too long you'll find the dungeon crowded with enemies!
