Strangely, I kinda like this track actually. I don't like how the cross-shaped collapsing thingy says "Haha, got you - surprise!" (=be consistent and fair) and I would hate being the scientist operating the stargate who always has to climb over the pipes (=have your obstacles make some relative sense) and I also find it weird how the humans and aliens would build their whatevers only two-dimensionally (=work on your visuals), but.. still, I had a faulty first run and the track invited me to do a zero fault. Not many tracks on TC currently achieve this

The redeeming feature here is #1 that you tell a story and also from your first track I get idea that this is your thing, so... go on with that. And #2, your obstacles are within one category, both style(?)-wise and in regards to difficulty, which is a big plus.
Can't you make the UFOs at the end explode/break/change their glass domes to a broken variety?
