From The Great Lange:

Sonic Utopia is an experiment that not only tries to expand on Sonic gameplay in an intuitive way in 3D, but also aims to capture the best of Sonic’s style and tie it together in a cohesive experience. Nearly everything in this demo, from art to sound to the gameplay engine, was made from scratch.

I created all of the models, animation, and most of the textures and sound, as well as the music.

The 3D Sonic engine and the gameplay driving this vision was created by my programmer fellow Murasaki.

We’ve been working together on this for a while and we’re glad to finally share it, with a debut at SAGE 2016.

For those interested, an early demo of the game is available right here (in the description) (I scanned the game with both Windows Defender and Malwarebytes before trying it out for the first time.)
