Congratulations for your hard work.
I have to say that your game is much deeper than what I would expect from the first look of it...
And I did decided to give up while stuck at first scene, before I checked the comments....
---------------
The game is quite complete in the sense of story and challenge. But those mechanics wait in the second scene, after you have to work out the "tree jump" trick by yourself. (Not really yourself, though as the second NPC would tell you.)
This is against the way we do game design usually.
But wait, it's a meta game, it feels like finding an Easter egg unlocks a whole new world!
You are supposed to miss them if played commonly. Maybe never notice them. From some perspective they are not really part of the game.
---------------
From the second scene, there are quite solid level design around the simple mechanic of "close button" which quite fits the theme. Though they are really kind of a bit hard.
It really feels good to unlock cursor. (I guess this is not the only entry that thought of cursor as meta element).
PS: I couldn't beat the boss.
