Hello. As I promised, I played your game again so that I could show you where (it seems to me) you can fix bugs. At first, when we start in the first room showing three portals, we have a significant loss of framerate (first picture). I assume with 3 big portals, this is too hard. I noticed a recurrent graphics bug which you can see in the picture (second and third pictures). I took a shot only two times, but this is really recurrent. Do you see the thin lines? In the last picture, there is a problem with your controller. I guess that you could fix it quickly by changing mass or gravity value because the player doesn't slide along the tunnel - he skips and it is really disturbing (last picture). Also at this stage, there is another loss of framerate. For me, it's no good. Your portal code is too guzzler :) You are wasting your resources somewhere. However, all these problems which I quoted are not too frustrating. Your game is overall very good. I wish you the best in developing it. Bye ++
