Thanks for your reply :) I tried many ways to open it and finally find out how to launch the game. Instead of launching game by click on the game icon, I have to right click on the icon, choose Show package contents, click on the folder named Contents, double click the exec file of CursedLands in the MacOS folder, then the game will automatically launches through Terminal. Just in case if someone get into the same trouble as me, this could be a method to solve their problemsXD. Thanks for all the efforts you put into this game. It is an excellent game that I really reallyyy enjoy playing it!
