You can find this new installment of the game at http://www.yoyogames.com/games/launch/47516
As of this writing, the game is still being virus scanned and is thus inaccessible. However, it should be good in about ten minutes.
As always, I've changed the link in my first post to the one for the new version.
If you need a save that proceeds from after the boss battle with Grafted Magehand, just post here and I will assist. Right now, however, I have to get off the computer and drive over to work.
And again, any suggestions for improvement are welcomed. Before I work on the final portion of the game, I am going to go over the previous sections for errors, glitches, etc., so don't be shy about sharing your reservations.
Oh, and once you beat this new boss (who is a ninja) you'll be transported back to the very first room. Don't panic; this is supposed to happen. In the very next release, a platform that will take you to the final path will appear in this room after all four bosses are defeated.
VERY IMPORTANT EDIT: If you downloaded the game between the creation of this post and the modification of this post, please redownload. The version I uploaded yesterday had some problems wherein valuable save data could be deleted by pressing certain keys. The version I have just uploaded a fixed version that should work.
