It' okay. The Hammerfight doesn't seem to properly work, the controls are meh. The Crayon one is basically a paid version of a free game. VVVVV and And Yet It Moves are challenging for sure and Cogs, well, I haven't played it yet.
Just beat Braid for the first time, and dear God that game was so well put together. Hands down one of my favorite games from everything I downloaded. The other games were alright, but couldn't keep my attention. Braid had an incredible storyline relating to the invention of the atomic bomb, fantastic design, amazing soundtrack, and fluid game play. Seriously, solid. Definite 5 stars.
