Quick click 4 - Spiderhead (2005)
Actually a sort of unofficial Spinoff of the Fishhead series of games. Blackgaze did a wonderful job with this game, pushing the limits of TGF1 (keep in mind TGF1 doesn't support layers and has a 262 active object limit among other limitations)
Some small annoyances are that stunning enemies by landing on their heads is almost useless as they've recovered and shot at you by the time you land, and the kickback from guns is too strong and doesn't add anything to the game anyway.
Great music by Josh Welchel (i can only assume as it sounds like his The spirit engine work!)
