Revises how the night time curse mechanics works in Castlevania 2. Zombies still appear in town at night time. Monsters still get stronger, and drop better hearts at night time. You can now trade for the Blue, and Red Crystals at night time. As well as enter the merchant's houses at night to buy there goods. Good for people who struggle with this game to get the best ending. Also good for speeding up how long it takes to playthrough the game. Tested with Bisqwit Castlevania II English Re-translation (+Map) hack.
