Rochard - $9.99 - 75% - $2.49
Rochard is a side-scrolling space-platformer with inspiring graphics and gameplay. It's something I'm currently playing through and thoroughly enjoying.

A puzzle-solving platformer, Spectraball is the only game on this list I must admit to not having played. For this price, I soon won't have to though!

Finally, (just in case you're new to my posts) Dog Sled Saga is an adorable 8bit masterpiece, and you can get the game for just $5. Hurry, their Kickstarter only has two days to go!
