This is my first official Cave Story mod, known as Lunar Shadow.
You could say it's inspired by the Castlevania games; it's also inspired by one of the mods my ex-boyfriend had made in 2012, Shadow of the Stars (hence, why this mod's name is Lunar Shadow).
This mod is a tribute to him. Sure, there are a lot of people who hate him (including myself), but still... may he rest in peace.

SCREENSHOTS:
I'll eventually put up some screenshots of the most recent version, so please be patient until then.

VERSION HISTORY:

• 0 : initial release on 16 January 2015; ended at the boss room of the Entrance area with Igor as a "boss"
• 1a: released on 17 January 2015; had fifteen Entrance rooms (out of seventeen) and had the actual boss of the area, Xyz
  1b: released on 17 January 2015; fixed a major bug in the starting screen which prevented one from leaving the house

  Size: 1014.38 KB (zipped), 7.72 MB (unzipped)
  All of the Entrance and Laboratory maps are accessible. Some of the areas inside those maps, however, aren't necessarily accessible. It's impossible to go to the Servant Quarters or Reservoir or Tainted Garden.
• Lunar Shadow version 1b
  The second release.
  Size: slightly larger than 945.94 KB (zipped), 5.42 MB (unzipped)
  Most of the Entrance area is accessible, with the exception of two rooms. Fastest update of the mod yet. There's slightly more text, now. The other areas are inaccessible, so it's currently not possible to go to the Laboratory or the Servant's Quarters.
• Lunar Shadow version 0
  The most basic demo. It bears the mark of Kim.

  The demo is just to show that I'm working on the mod. Playable up to the boss room of the Entrance area. Said boss is not the intended boss, but whatever. There's also very little dialogue - just the save points and leaving the castle. Also, this was just made in two days, which isn't a good thing, really... rushing things tend to make them of horrible quality, but I'd at least like people to know about it and be able to play a bit of the mod.

If you want to put up a mirror link, ask me first, and if it's done, post the link in this thread so that the forum staff and I can put it up in the first post.
