Sonic XX, or Sonic XX: The Dress-Up-and-Down! or The only Rule 63 Sonic game where Tails gets to keep his dick is finally here!
First of all, you may find it odd that the game doesn't have much of a music... It actually has only one and it's on the intro. The reason for this is that the way I make my Flash animations are kind of unorthodox, in a way, as I dump all my drawings as transparent PNGs into the animation instead of doing my drawings in Flash -which would save more space. In a blink of an eye, this project grew VERY big in size. The game is already 9.4 MB so I had no choice but to stop adding more and more to it.
The game might confuse you here and there. Don't be shy to check the Instructions option from the main menu, and the Hint button every time you unlock something. Hint button does not actually hinder your game experience; it AMPLIFIES it, because nowhere else in the game you're clearly given your TASK so that you can unlock more stuff.
One of the most nefarious and notable bugs in the game happens when you unlock your FIFTH emerald. I couldn't eradicate it but I can show you how to AVOID it. You have to do something SPESIFIC to get that emerald. When you FIRST do that, do NOT change backgrounds till all the animations are over. If you do it, it won't show it as you truly unlocked everything. You can still set things right if you do that same spesific thing in that spesific background again.
