Picross e is great, if you like Picross. Which I do.
The Starship Damrey is short, and kind of interesting. I don't know if it's worth however much it's selling for, since you can burn through it in maybe an hour or two. At least, unless you get stuck doing something stupid like I did, walking past a super obvious door over a dozen times before noticing it.
The Denpa Men: They Came By Wave could be cool, if you have the right setup for it. I can't say one way or the other, though. The fundamental game mechanic depends on you being able to detect a ton of different wifi networks (like you could if you lived in, say, an apartment building in Tokyo). Being in a house in the suburbs, I can see my network and occasionally the neighbor's, so I can't do much with that game.
If you liked that dice rolling game, you might like Etrian Odyssey IV: Legends of the Titan. It is more or less a grind-fest though.
