Hi Bruno, first and foremost, thank you for all the kind words, they really mean a lot!
Also, thank you for pointing out the errors! I will be fixing them in the 1.1 PDF of the game as soon as possible.
Regarding the "page 8 Coins"; the 20 Coins for Additional Equipment are a plus, you get them in addition to your "starting 3d10 Coins". So basically, you get to spend 20 coins before the adventure starts, and then you get an additional 3d10 Coins when your adventure starts. Hope that helps!
I will probably add this to a FAQ document, thanks for pointing out!
Regarding the open license, I'm very happy you liked it! I am also considering the possibility of running a jam for STRIGA in the near future, so in that case, see you there!
