Sonic 1 NAC Tiny Version (Tiny as in short version) is a hack based on Sonic 1 made by Campbellsonic is a simple but advanced sonic 1 hack that has different events and concepts with in each level. Therefore making each level different and unique to the standard level edits that you find in must hacks, especially some of mine. Hack Story line:One day sonic decided to take a break from his friends and the stress that he has been going through, and went back to south island. however when sonic had arrived at south island he noticed something was different, everything seem to have changed colour and seemed to be a lot darker then it use to be, And so he decided to explore. After spending 10 minutes exploring the changes; sonic noticed the that the badniks that he destroyed before had reappeared in green hill zone. Then sonic realized that robotnik was back to no good once again and goes to save south island once again. Level Information:You may notice that all of the main levels have a wall that seems to be unbreakable at the end of the level, this is because your required to find and hit an "S" monitor in order for that wall to become breakable and before your able to finish the level. Act 2 of the main green hill zone will start off normal but then you will given a platforming challenge. Act 3 of the main green hill zone is a auto running level inspired by sunset park act 3 from sonic triple trouble, where you have no control over sonic's speed or direction he is running in, all you can do is make sonic jump.Credits:Beta Tester: Sarah Mckinney (KosmoF)
