The goal is to survive through 6 boards with as much gold and treasure as you can.
Best thing to aim for starting out is to get 25 gold through tile events, then press START (Enter) and go into ‘Items’ and buy a treasure, to gain a new ability.
At first your input is to just choose directions at intersections, or what to do on certain tiles, but once you’ve got a treasure you can use its ability to help in specific ways (e.g. move a specific number of spaces for a mana cost).
More treasures mean more options, and the game is mostly about strategizing where to go and what to use and when.
I will likely expand on the tutorial in future, so if there’s anything specific that’s unclear or confusing I’ll try and clarify.
