This is a collection of current information about Sonic Hedgehog 11.
Overview
Sonic Hedgehog 11 features a character called "Blue", who is an edited version of Sonic, having the tan parts of his body swapped for more blue. Blue also has a few other design changes from Sonic, including the lack of ears and nose, different shoes, and bigger eyes, but for the most part is just an edited Sonic. JDP said that the title screen features an image of the Sonic artwork from the boxart Sonic Adventure, edited to look more like Blue (although it isn't entirely accurate to Blue's in-game sprite or other art of him in the game), and with the text "SONIC HEDGEHOG 11" below it, while ScorchXX said that the title screen is taken from Sonic R, although with "Sonic R" text lazily replaced with "SONIC HEDGEHOG 11". Waiting on the title screen will give you a quick synopsis of the plot written in Russian, reading:
"Oнeт! Дoктop Яйцeгoлoвый вepнyлcя зa cтapoe, нo y Coникa и Taилc дeл нeвпpoвopoт! Hoвый дpyг Coникa Cиний дoлжeн oтпpaвитьcя нa пpиключeниe cквoзь Eвpoпy чтoбы ocтaнoвить злoгo дoктopa, нo eгo пpиключeниe нe бyдeт лeгким! Пoмoжитe ли вы Cинeмy пoбeдить злoгo Дoктopa Эгг мaнa? Или пpидётcя eмy разорваться?"
Disregarding the morbid ending to the synopsis, the setting of Europe is mostly just an afterthought, as the only semblance of Europe is likely completely accidental due to stolen assets. It also erroneously refers to Tails as "Thales".
The game features 10 zones, with only some of them being a direct lift level design-wise. However, the new zones are not exactly polished. The game is said to have an erratic difficulty curve, with some levels being considerably easier than the ones that they were placed in between.
Zones
Emerald Hill Zone (Act 1 is Hill Top Act 1 with Emerald Hill's background and palette, Act 2 is Emerald Hill Act 2)

Origins
It's somewhat debated who made Sonic Hedgehog 11, and whether or not it exists at all. The person who first documented the game, a forum user named ScorchXX, claims that the game was on a Chinese multicart and that the credits say it was
created by "Ping Technology". However, another user named JDP found the game built-in on a Russian Genesis clone, and claims that this was the origin of the game, with this version crediting developer "B4A". It is believed that B4A is likely
the true developer, as a majority of the game's text is Russian, although B4A is not known to have released any other bootlegs. Some people believe that Sonic Hedgehog 11 is just a hoax by the two users, as these are the only two known
copies of Sonic Hedgehog 11 as of writing, and it has yet to be dumped online. ScorchXX claims that the game caused his multicart to start malfunctioning, while JDP simply never bothered to dump the ROM.
