The D-sides are a custom map pack for Celeste (think Kaizo maps). They are a lot more difficult than regular Celeste, and some sections are very precise.

While there is new ones, especially of 3D,6D,8D and 9D, I wanted to get this out since we've been working on it for a long time. Expect a video of the new ones in a month of so.

This is a TAS of all of them. It is over 2 minutes faster than the previous released version, with time saves of:
City: 5s
Site: 3s
Resort: 17s
Ridge: 22s
Temple: 14s
Reflection: 20s
Summit: 53s
Core: 1s

I've been working on this on and off after the previous release 9 months ago. Huge thanks to Fishmcmuffins and Euniverse for helping with various levels, and Rubydragon and RichConnerGMN for some strats. I hope it is enjoyable.
