That was actually really good. Some tricky tests, mostly ones with red herrings that mislead and confused me - I did look at walk through video for help on about 3 occasions. Otherwise it was fun, quirky and epic, cool parts such as special new weapons/mechanics, voice-acting, set-piece sequences and call outs. It was postmodern, at times reminded me of Stanley Parable.

Recently upgraded to SLI 980 Ti's and this test recommends that I upgrade my graphics card!
Turned off G-Sync and suddenly it's perfect.

I have just completed all of Quanton's tests! It was a very challenging, exhilarating and satisfying experience and I now feel quite accomplished.
I love this game! It trolls you, in a fun and friendly way, and keeps pushing you to do better. As the difficulty kept rising I was laughing, thinking 'this is ridiculous!'. However, sure enough, I kept getting better with practice and working out how best to pass each test, until that part felt easy and I was cruising through to the next seemingly impossible part.
The game is perfect. Nothing could be done to improve this.

I noticed a few bugs:
Sitting scientists' height - 1 floating above another embedded in his chair.
A door opens in a garage and collision detection moves it upwards.
Conveyor belts in Xen - barrels moving at a different speed to the texture on 1, on another the player is moved at the wrong speed.

I love the graphical (e.g. water!) and physics improvements with Source engine. Still an awesome game, as ever.
Previous time I completed HL1 was half my life ago.
