Cute. My first death I got stuck in a room that I couldn't leave and had to reset the game. I only got to level 2 or 3 though and couldn't figure out what to do. It was a level with one set of spikes on the bottom left, a red QR code on the right and when you died there were platforms around what looked like a TV screen in the middle but I couldn't figure out how to get to it.
Other people have said they finished though so it must just be me!
I liked the way the levels switched when you died and I thought it was well polished
