Sonic the Hedgehog & Ashuro is an awesome ROM hack based on the classic Sonic the Hedgehog. Created by Ashuro from SSRG (Drakughost), the game features 2 characters and 2 universes on one single screen. The game features custom and special stages with 3 acts that take place during the different time of the day. In this game, you will control both Sonic and Ashuro. The two characters have similar movement but use a different approach on various obstacles like water and high places. If you can collect 50 coins during the gameplay, you will transform into a more powerful form. Good luck!
