Genesis Sonic Engine (Ver 1.3) except way too fast

Instructions

Instructions are in game. (Except for pressing the P button to change the level. You can do that too.) Following is an update log: Versions Fast 12 to Fast 16 (November 8th, 2017) - Jumping from the ground while boosting no longer triggers a boost jump - You have to let go of the up arrow first - Holding the up arrow while idle/standing no longer drains boost - In fact, it'll actually regenerate ever-so-slightly faster - Less sensory abuse when going fast - (Slightly less) - Tweaked some after-image sprites and the such - Added another level - ...okay, two more levels.
