I highly recommend playing the original game or the retranslation mod before playing this version as this is not a 1 to 1 remake.
This version is quite buggy and is in a constant state of being worked on so while you can technically beat it from start to finish it has a lot of issues/bugs currently. The original or retranslation mod will be a much better experience for you as a player, as version 5.0 is still some time before completion.
