I also tried to dowload the game in various browsers, then i finally managed to dowload it on Chrome, but then i opened the game, played up to chapter 3 or 4, saved the game and closed it, when i opened it again the save just disapeared and now i have to play everything again. The worst thing is that the "skip" option isn't even working.
Now i will wait until the dev says she fixed those things, because i aint wasting hours playing all of that again :(
