The game is in fact so unoptimized, it really is unplayable to low-end devices. Even attempted to press ESC, assuming settings will appear, but it was an inventory. Turned it windowed, lowers its resolution, still laggy. I kind of hoping that the game gets the same settings as it had previously, removing few of the shaders and effects.
I wonder, if someone was able to drop every animation the developer uploaded, since the previous animation about the 3d version does not include the ones in fantia.
