The game is not bad, it works fine and has somewhat a different aspect than others, where you slowly explore the map unlocking new tiles. But i really dint like the random symbols and the lack of any explanation on this, even figuring out how / why the keys exist took some time, the idea is good but not too many people will like this approach, it dont need to be a game that hold the players hand all the way, but it need at least a proper introduction at the begin.
