Really great game! I was relieved to find out that it took you 5 hours because I couldn't comprehend how so much could be made in 3 hours.
I love that the final level has a bit of a plot twist with you having to break the portals instead of fix them. Dialogue was great and the visuals and audio were both very fitting. My only complaint is that the hitboxes could have been a little more forgiving. Overall though it's an insanely impressive game to be made in 5 hours.
