An idea
Here are 2 ideas:(1) make the nights area a real nights level, where you activate it by the same means as the level in the fangame (by hitting the srb2-ified palace) then destroy the ideya capture, and exit the way you came in. (2) have someone rip some models from each of the game's included, and have the main character(s) doing something relative to the series (like beat buttons and amigo from samba de amigo and ulala and a morolian dancing, as well as props from space channel 5), and if they can get slopes and looping right, they could be inserted into sonic as well. Plus, for chu chu rocket, make boosters that look like colored direction tiles!
