After 2 weeks of playing the game, I finally beat the game! Took me long enough, since the translation was pretty hard, but I managed to finish the game and understand the basic premise of the story.
The plot is really interesting, though I'm still a bit confused about the story of Eddie and how his past connected to Xavier's backstories. Other than that, everything about the plot, the history in the game is very well done in my opinion. The whole brain transplant project is kinda scary, Terry's motivation in general is understandable, Richard is Xavier's grandson is a great twist. I love how everything in the game connects. Overall, the plot is excellent.
Puzzles are fun, but sometimes it can be frustrated.
My only complaint about the game is the monsters. Sometimes they are very cheap in my opinion and the more I played, the less scary they are.
Kinda sad that the game doesn't have an English version, if somehow the game gets a remake or at least a translation, it would be very neat.
I really like the game and will look forward for your next projects!
