I got both of the endings muffin and super filly
The only reason I took off two stars was:
1. The dragon didn't blend into the scenery (was clearly ripped from another game). I know it's a little trite, but games this awesome should really have every character and background well blended.
2. The Blank Flank ending. DON'T FLAG ME, GUYS!! Just read it. The fact that there's an option to get a 'game over'-type ending is pretty cool. But, I really wish there had been a chance of escaping.... Luna using magic, or something (besides, Celestia would never banish Luna into the Everfree forest). Maybe you could add a minor change at the ending to make it possible to get back out? A "good" Blank Flank ending?
Got all the endings
First I got the super filly ending, then the muffin one, and lastly the blank flank ending, and I got to say my favorite is the blank flank one, it didnt scare much at all but I liked how you transformed the fun-loving ponies into these demonic killers. You sir, have earned my respect. (I had to look up the blank flank ending one though)
Got The Ending...creepy much?
The real endings were funny and fun. The blank flank ending was... terrifying....
Good fucking job, no sarcasm. This is the best thing I've played on NG in a while.
