Oh man I loved this so much! It really reminded me of some Psychonauts levels like the mail room in Psy.2, or Ratchet and Clank (esp with the helicopter), or I have memories of a Toy Story PC game from way back (googling it I think it was the Toy Story 2 PC game from 2000). I struggled the first few minutes but I had an aha! moment and everything clicked, and by the end I was zip-zopping all over the place. The ending was unexpected! I won't say more in the comments, but I thought camera movement and animation were really good.
I ran into a couple bugs, but just minor: I was on one side of the plaid couch(?) and the camera moved so it clipped through, and because of that maybe I accidentally grappled myself to the other side of the plaid and flung myself to my doom. Oh well. Also, I was able to trigger the 2nd to last cutscene again (when you're on top of the box). I walked in a circle up there and must have triggered something.
Super great job, very inspiring!
