I completely finished your game. All 3 endings!
For Jay6 (Creator):
To be honest, I'm not really bitchin' on graphics. I did found Jade pretty contra-pony (Her colors made me think so). Also, the Super Filly art sucked. I was neutral about the Muffin art, and with Blank Flank, you gave some pretty heavy shit. Too bad it was a bit blurry. (btw could you please PM a link to the Screamer? I'm going to set that up as my wallpaper :D)
The 8- and 16-bit music was 1 of the things I liked about this game. I especially liked the Pokemon Boo-boo-badingding-machine sound, while preparing the muffins. I liked that extra touch. The stories where... random. You have just invited everyone to come to your party, and suddenly OMGWTFBBQ A FUCKIN DRAGON APPEARS U HAZ TO KILL IT NAO! (Super Filly). I'm not going to spoil the secret endings. Blank Flank did get my aortic pump working overtime, but the screamer didn't affect me. I also liked the references to Cupcakes.
For the gamers :
Here a no-spoiler guide for the endings :
Super-Filly : Get everyone on the list invited. Talk to Pinkie.
Muffin : Make shit-muffin. Donate to Derpy.
Blank Flank :
1) Set clock between 11pm and 5:59am.
2) Start game.
3) Hear every piece of dialogue including that of Pinkie before you've got all the invites.
4) Make good muffin. Donate to Derpy.
5) Check every piece of dialogue out again (also Zacosa's). Make sure not to trigger Super Filly.
6) Go to the Evergreen forest.
NOTE : Once you've reached the edge of Evergreen, and triggered Blank Flank correctly, it's one-way.
