Perhaps one could even say you've got every last detail of those first few seconds of Sonic 1's iconic opening stage memorized. Well then, you shouldn't have trouble spotting anything that doesn't belong, right? The rules are straightforward: Don't overlook anything unusual If you find an anomaly, turn left immediately If you find no anomalies, continue to the right Exit through a normal Green Hill Zone Act 8 This hack took about a month to complete, and it was directly inspired by the Japanese indie game The Exit 8 by KOTAKE CREATE ( https://store.steampowered.com/app/26... ). I was fascinated by the simple premise yet surprisingly engaging gameplay loop (pun intended), and wanted to try my hand at making a Sonic rendition of it. However, due to the more colorful nature of Sonic, this hack leans a lot more into absurd/entertaining rather than horror/creepy. Making this project was without a doubt the most fun I've had developing a new Sonic ROM hack since I've finished Sonic ERaZor 8. I hope you'll enjoy it too!
