To continue on with game breaking glitches as or321 was talking about, there is a glitch to move through walls. However, it can only be performed when there is a portal. To go through a wall where the portal is on the opposite side, the mouse needs to be moved (over what I presume to be a single frame) from the player to the portal. To go through a wall with the portal on your side, the player needs to enter it and then re-enter it. At this point, the mouse needs to be moved across the wall in a single frame. As an example, my time on level 30 is 0.55 seconds. Yellow world still remains the least broken, but is significantly more broken with this glitch.
That took me a while to figure out, that's quite an impressive find, honestly. Working on a fix right now. Thank you very much for reporting! EDIT: It should now be resolved. There was indeed exactly 1 frame after each warp where the game would not check collisions between the current and the previous positions of the player.
