Fieldrunners

Tower defense game.

PROS: Pretty colorful graphics and smooth controls, the promise of new content that has been partly delivered on.
CONS: Lack of depth-- only 4 weapons with 3 upgrade levels each.

Orions: Legend of Wizards

Collectible card game with base-building/base conquering overlay.

PROS: CCG component works very well on this platform. Cards have decently varied abilities.
CONS: Base building and conquering component isn't exactly compelling and honestly seems rather unnecessary. As is usual for CCGs, some balancing probably would help. Themes are not cohesive in each card type. Documentation could have been better, and text on cards is sometimes ambiguous in meaning.
