At least the game is beatable. 1 of the bugs is present in any playthrough though. In Gaia's flashback if you save in the bathroom - you're not getting out. The cutscene activates after opening the door. After saving it resets for some reason, so after trying to open the door from the inside - Gaia gets in the water and doesn't get out even after the end of the cutscene. You can only change direction, but movement is impossible.
