Yes, I will complete the game before the end of the CaveJam.
You will return to the burning tower in the last room (the dark room that is now lit by the fire) and you will find an object that will tell you where to dig with the shovel (you no longer need the torch and I will use it differently). I must also put the epilogue and prologue that will explain why this game title and why the troll has been transformed into stone, but also the essential role of the pearl in this story, which I did not have time to develop; a lot of work to do!
