The version played by SkyDoesMinecraft was requested so here it is, this version has no comet observatory as a central hub and instead works more as a sky block survival map with branching options. Though a less up to date version the game play might be overall slightly better as switching to adventure mode completely changed the map for better or worse.

I would assume it works in 1.3 Im not that great at technical stuff so Im not completely sure but I read all the changes and nothing should effect it either way I will test the map to make sure everything still works
you mean remake a sonic game in minecraft? Would definitely be fun using single player commands to set speed and make your character run really fast but would take along time to make.
I did start making another map awhile back called Alphabet Survival in which you have to make it from A-Z on giant floating letter made of blocks whose names start with the same letter. Maybe I will finish that map first.
