This is a ROM hack of Sonic the Hedgehog for the Sega Mega Drive, that features Ray the Flying Squirrel, who takes the place of Sonic the Hedgehog. Unlike Fabricechaotix' 2007 version of Ray the Flying Squirrel in Sonic the Hedgehog, which only had SegaSonic the Hedgehog to reference, this one used Sonic Mania Plus as a reference, and also pulled assets from it, such as art.
