We certainly didn't expect Puzzle Quest: Challenge of the Warlords
to be released on DS this week, mostly because it was released on DS in 2007. But new publisher 1st Playable Productions has surprised us all with a DSiWare version. If you missed out on it then, you can get it now without undertaking a heroic journey to the store.
In addition to subverting our expectations with a "new" game from four years ago, DSiWare also hosts a shmup about conserving ammo.
Meanwhile, WiiWare features a game about ... pouring liquids. But, like, with puzzles and stuff.
