Some questions that I have answered because you might ask:

• Why did you use that logo?
  The short reason is, because I can. The long reason is that this logo meshes much better with the NES' aesthetic, than the new logo. The new logo would look downright weird when downconverted to an NES-compatible screen.
  Also, I just think it looks cool.
• Which Chapters will the demo feature?
  It is expected that the demo will feature Chapters 1 and 2 of Celeste in their entirety. If there is enough time, Chapter 3 may also be included in the demo.
• Do you plan to publish this project as open-source?
  Yes, I do! In fact, I'll do it as soon as the first demo is released.
• Where did that logo come from?
  Variations of this logo have been used for promotional material for Celeste during July-September of 2016. See:
