Nice concept! I liked the variety in puzzles, though I wish you'd explore some elements further (I think the purple portals appeared only in one level). The "old TV" visual effects were good, but a bit overbearing, making the game a little hard too look at. I don't think I should have earned a jar if I picked it up without finishing the level, felt like cheating.
It was a bit hard to deduce which portals connected with each other, I would've thought that first portal connected with the second one, the third with the fourth one and so on. I had to brute-force a level with 2 green and 2 blue portals because of this.
Thank you for avoiding hand-holding and letting me figure things out for myself.
