If anyone is looking for cool indiegames, many of which don't get a whole lot of attention from the press, here's a big list.
Of the ones on that list, I would recommend:
Cave Story+ (Probably my favourite out of this list. Great gameplay, music and characters all around. Extremely difficult on higher difficulties, but it's a testament to the quality of the game that I bothered to finish the game on Hard).
Crypt of the Necrodancer (Roguelike + Rhythm. Awesome music, cool gameplay.)
Dustforce (A bit like Super Meat Boy, but more difficult. Controls are a bit more flaky but they never annoyed me).
FTL (Roguelike in space)
Guacamelee (Cool metroidvania action game. Also, you can transform into a chicken)
La Mulana (Old school metroidvania game. Long and incredibly difficult to complete on your own. I certainly needed help.)
Nimbus (You're in a rocket. Use momentum to get to the finish line. Surprisingly fun.)
Papers, Please (GLORY TO ARSTOTZKA)
Risk of Rain (Very cool game until you've gotten all the Artifacts. Then it becomes a snoozefest unless you impose restrictions on your powers yourself)
Before the Echo ($0.99! Sequence on that list. Rhythm game where you control three DDR-style panels of arrows to battle enemies. Cool game with cool music)
Shovel Knight (Megaman, but with a shovel.
SPACECHEM (Only $0.99! My favourite puzzle game ever. Infinite possibilities to solve and optimize the puzzles. Will get fiendishly difficult fast.)
Spelunky (You will die. A lot. But it will be your own fault every single time. Randomly generated levels keep it fresh and exciting.)
Super Hexagon ( $1.01! Definition of pick up and play. I have this game on my tablet as well. I've still only beaten the last level a couple of times as it's insanely difficult, but very fun)
Toki Tori 2 (It's only 75 cents atm, and that is easily worth it. The game mastefully learns you all the new mechanics you need to get through the game. You can go everywhere from the beginning, but chances are you won't be able to figure out how right away)
I didn't expect this list to get this big
