When you beat the game, there's the cutscene about that stickguy with wings as for the player.

The player is @JustKim (known as Stick-Kim). I talked to him in discord about this game in November and how it suppose to be.

He also said: Will I be in the game as T-Pose? But after all it happened!

And that's how the game is suppose to be like that lol.
