Having submitted a sokoban game for the jam, when I saw that you could push boxes, for a second I thought, "Cool, another sokoban!" It seemed you were going for more of an immersive experience than a puzzle. The effects are awesome, and I don't have much else to say besides what has already said. I definitely agree that the missing colliders were immersion-breaking, 

It was hard to tell what to do. The text for the controls stayed up the entire time and gave no indication of what the mechanics or goals were. Then I just won upon finding the spot where the colliders didn't make sense. I think the idea is really nice, but the execution could've used just a bit more to get it right. It also is not good design to trap the player on the ending screen with no way to leave. As a general rule, if your player has to use Alt-F4, there's something wrong.

Really liked how you incorporated the two-color challenge. And it's super cool how when you get near the chair, color comes back to the scene. I guess it's like you're remembering when you're sitting in the chair! It's a nice touch how the boxes you move make a couple different sounds, too. As far as criticism goes: some box colliders on the furniture to keep me from walking through them would have made the experience more immersive. But all in all, I liked the feel of the game!
