Sonic Lost World producer Takashi Iizuka has shared his initial design worries for the game’s free Zelda DLC . In an interview with 4Gamer, Iizuka said that the team wanted to distinguish the differences in the Zelda level in comparison to the normal Lost World zones.

Though the appearance of rupees and enemies in Hyrule field would be enough to set any Zelda fan’s heartbeat racing, Iizuka said that those who are less familiar with the franchise may not spot the differences from the off-set. So the team designed Sonic in Link’s famed green tunic, but the producer still had design woes over how to implement these features to great effect.

“While talking with the designers, we were wondering how we could have Sonic wear these clothes and look normal while covering his spikes. In any case, I was definitely worried at the time of designing.”
