[quote name='Mr Unoriginal']So what's good in the eshop? I have about $10 to spend there. I have Crimson Shroud which is really good. I know there is Crashmo, but I'm not sure if I want my head to explode while playing a game.[/QUOTE]
I've got Pushmo, Crashmo, and Mighty Switch Force.
Crashmo can get a little tough but it's not like, say, the 60 point puzzles in Layton. The bonus with it and Pushmo is you can get new puzzles online for free.
Mighty Switch Force is good but it's also short. The great things about all these games is the stages only take like a few minutes to solve, so they're good on the go.
I also have Cave Story which is a fun Metroid style game
