A game from me to you~

I had already done that.

I got it to work after all. It turns out I was just herp derpin with the whole source thing, since it was just telling me to extract the files to a folder so I could play the other Game.exe. Derp.

...I killed Fangblade twice because I went back into the square. Epic lulz.

That's not a bug, that's the maze part of it all.

You should be able to fight Fangblade more than once in that map without leaving. I have the steps required to enter a battle set to 15 and there is no limiting factor on how many battles you can get into with him.
