Feel free to take these sprites and use them, and ONLY remix this if you want to add more. The sprites mainly came from the Spriters' Resource at sprites-resource.com, so if you have any from there and want to add them, please do so, but be aware that it has become impossible to properly center sprites.
Thanks to Scratch 3 it is now impossible to make sprites properly, in regards to both colouring and centering. I've had to abandon this project because of it. UPDATE LOG 9th March 2019 • Updated the project so it isn't AS broken by Scratch 3. 15th December 2018 • The Tornado sprites now have a left rotation that doesn't result in the text on the side being reversed. 2nd December 2018 • Miles and Tails are now two separate sprites. • Made the timings of the fire shield sprites a bit more accurate. 18th-21st November 2018 • Recentred the running and spinning animations of the Sonic 3 sprite and variations • Restored some of Mania Sonic's animations • The S2 Beta sprites now turn to look at you • Added Spike (That Badnik from Spring Yard Zone) • Added Chopper the fish from Green Hill • Removed the pop sound from some things • Added Cucky, 3 Flickies for each character, Pecky, Pocky, Ricky & Rocky (Chicken, Birds, Penguin, Rabbit, Squirrel & Seal) 16th November 2018 • Yellow Socks Knuckles is complete 20th October 2018 • Sonic from Sonic 1 can now be Super Sonic!
