I'll be honest, I was confused about what Kendela was doing when I was getting the keys. Also, why were so many of them in the same spot? Likewise, why is the Doomsday music from Sonic 3 playing? It's definitely the mod ever :). I made a video btw.
I actually made a remastered version. Which also fixes the key glitch that allows you to instantly get more keys then you're supposed to and then go to the final level instead of actually playing the game
