Found a hidden developer room! (SPOILERS!)

[Hex]

In Chapter 6, in the room with the old lady, climb up to where the elevator fell. In the next room, do a dash-walljump on the first block that juts out to reach the second, then jump to the third and over to the right to reveal a hidden alcove. From there, do a dash-longjump to the other side and then dash up in midair between the spikes to reach a secret room filled with characters from the developers' other games!

Also, I found a hidden screen in the Prologue, other than the one directly to the left of where you start:
After the part where the ice block falls, climb it to reach a screen with a bunch of birds flying around. They reappear in the far right screen in the Epilogue around a giant nest.
If anyone knows of any other secret screens, post here!

I recognise Ogmo and the Towerfall character, who are the others?

The character with the shovel and white hair is from their upcoming game Skytorn

The blue on the left may come from Out There Somewhere

That makes sense, since Pedro Medeiros is credited for making pixel and UI art for this game, and it seems that Out There Somewhere is by him.

The white haired woman in a green shirt is clearly from Skytorn.

The red must be Meat Boy

Lmao
It's Ogmo. A char from a previous game by Matt.
The char is referenced in Meatboy though.
