WARNING: DESIGNED FOR MINECRAFT 1.7.2-1.7.10. Various elements of the map don't function in Minecraft 1.8 and 1.9 but the map plays pretty well so long as you change the game mode to survival. 1.7.2-1.7.10 is always recommended though.
SonicCraft is an adventure map which comes with 3 resource packs to be used with the map. The map and textures are inspired by the first four Sonic games for the Sega Mega Drive / Sega Genesis (Sonic the Hedgehog, Sonic the Hedgehog 2, Sonic the Hedgehog 3, Sonic and Knuckles). The map and resource pack have been in production since July 2011, and have since received over 175,000 downloads, and a huge amount of support (you're all great!)
The general theme of the map is an adventure-style map with plenty of puzzles and parkour thrown in, as well as many unique items from the Sonic universe.
SonicCraft is currently not heavily under construction, but a new update fixing compatibility issues and introducing new features is set to release some time in 2016. Any and all suggestions are welcome, particularly suggestions pertaining to new mechanics and items that could be added to the map!
Remember to read the README file for installation instructions. If you're making your own Sonic map I'd prefer if you used your own texture pack too, instead of using my work without permission - I'm only saying this because it's happened a few times in the past though.
