I really like this game, the portal feel is there and the dev commentary is really interesting.
There were some bugs but I am sure they will be fixed after the jam ends. Maybe there can be some mainframe like glados or the cube telling the player what to do when introducing new things and mechanics. I found the dev commentary about the pillows and box sound effects hilarious :D
ps. i managed to skip the exploding bridge by just jumping over to the other platform :D
