The sky background was later reused for the Pinball Bonus Stage in Encore Mode. Oddly, it does not have Mirage Saloon or Chemical Plant, both of which were playable at E3 2017.ĭifferent background graphics for the title screen leftover from the 'Discovery' part of development, with a slightly more geometric island and graphics of a strange Model 1 Genesis with a 32X and a Model 1 Sega CD emitting a beam of light.
Unused sprites for the game's title screen show the game's early name 'Sonic (the Hedgehog) Discovery', most likely left over from the prototype shown to SEGA.
