Flight's an upper-tier game of the launching genre. I BELIEVE I WILL REVIVE THIS THREAD A BIT!
Good stuff I have come across catching up on the last couple months of flash games posted on Kongregate:
Sierra 7: Part rail shooter, part sniper game. Shooting range challenges and actual missions, there's reasonable depth here.
Tasty Planet: Short little action game where you just roll over smaller things to eat them, like Katamari. The brief story is amusing.
Digital Upgrade: Dr. Mario, Puyo Puyo-style puzzle game. Matching three or more pieces combines into a piece of the next tier. Good luck making an Internet!
Exterminator: Rather bare bones tower defense game but the interface is clean and it's well-executed. Very difficult on the back end.
Aurora: Requires Unity3D and graphic-intensive. Build-your-own-universe sandbox, combining planetary masses and putting them into orbit around the sun to support life, you have a limited time to sculpt your universe until the sun burns out. It looks pretty cool and if you have a taste for these kind of games, have at it.
