Can we create a category where you can run all the stages with only one wing of light? I was able to run through Isle of Dawn - Vault of Knowledge, so it's not impossible. I've been doing a candlelight marathon with one wing of light for the last three days or so, so it would be interesting to have a category.

We could do that, but that would exclude Eden so I’m not sure how that would work. Would it end around the same time the Candle Wax category ends?

It ends with Vault of Knowledge as well as Candlewax. Eden requires twenty feathers, so it's impossible to go there first. Should I split the category into one and twenty?　 By the way, it was possible to go over the barrier with two flaps of the wings with the chibi mask. I'm still verifying whether it's possible to go over the barrier with one piece if I have the technology.

It is possible to enter eden by your own with one wing, however you would need the home portal. For New Game runs it would not be possible but it is for NG+ if you have the chibi mask

Yes, do with NG+. You also need to go to Eden from the home by the chibi mask. From the Vault of Knowledge, the walls are long and sideways, and I often landed on the ground below because I couldn't fly well, so I decided that the route from the platform is more reliable.(:3 」∠)
