The Good Ship Higgs Boson by Jezzamon 2012-05-01T12:00:00
God - that ending glitch left me with the biggest "Wait.. What? Did I miss something? Is this a new game+ thing?" reaction...
That said, it's a great VVVVVV-inspired puzzler. I pretty much speed-ran it through a second time JUST to see the real ending.
Others have commented on the lack of connection to the theme. I think you could have pulled it off if you'd just showed the exterior of the ship (or your position in it) at the start, and during some levels.
