Hi! first of all thank you for giving it a try!
1) Technically you start in the tile with a shelter (there is always one in the starting locations), which makes sense but I see now it is not clear. I will add this to the FAQ in the Designer's Notebook (coming soon).
2) The game is intended to be played using a traditional draw-your-own map, but if you choose to use the tiles (which was a stretch goal) you can just print more. There are copies of all the starting locations. however, if you are using the Playingcards hexmap, you just need to enter edit mode (the suitcase icon), click on the tile collection and add more tiles of whatever type you need. This will add the tiles to the holder.
3) This is an unforgiving game and it is designed for you to choose whatever is less harmful (or, at least, what you think is less harmful at the moment). If, nonetheless, you want to play the hardcore mode or you just can't decide, you can roll a d10 and let fate be your demise.
4) The lantern token is just a way for you to keep track of your character's position on the map (if you are drawing it). If you printed the tiles, there are tokens for every character. The bottles are the elixirs you can craft if you are playing the Apoticari.
I hope this helps! Let me know how it goes.
Thank you so much for your time!
