Quest For Chili Dogs is an infinite runner Sonic fangame released in December 2021. I solo developed it in a little under 2 months in the Scratch engine. It's about as good as it sounds.
A VASTLY SUPERIOR version is currently in development hell, and until that's done you can enjoy the half baked version currently available on GameJolt!
https://gamejolt.com/games/sonicqfcd/680609 This game currently only works on Windows, but when the VASTLY SUPERIOR version comes out it should also work on Mac, Linux, mobile phones, and in the web browser!
Poking around the main menu may allow you to play as a special guest.
WASD keys to move, space to jump, mouse to aim and shoot if playing as the special guest.
Known Bugs
High scores don't save.
Holding space after jumping causes Issues.
Game freezes forever upon death. Oops.
For fun, here's some footage of an earlier version of the game!
