  • Fixed Ring Timers and added quick blink animation
  • Special Stage jumping responds to button presses like the normal jump (hold to jump higher)
  • Sonic collides with water after being damaged
  • Removed speed cap (mentioned above)
  • Sonic now has the Super Dash Attack or Spin Dash from Sonic 2
  • Fixed the death boundary bug
  • Fixed the camera follow bug (barely noticeable in-game)
  • Fixed the water palette on the Title Screen to be consistent with gameplay
  • Spike Behavior fixed
  • Sonic’s walking animation has been tweaked to look like the 2013 mobile version and Sonic movie credits
  • Fixed a “remember sprite” bug where objects appear destroyed when they aren’t when RAM is full (only noticable in Debug Mode)
  • REV01 Background effects ported
  • Fixed scattered Rings underwater physics
