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.
- Overflow (Digital Leisure, 1 player, 500 Wii Points): Place objects to guide fluids into the proper parts of machines. Try not to think about how much your onscreen avatar is likely being mutated by contact with these mysterious liquids.
- Puzzle Quest: Challenge of the Warlords (1st Playable Productions, 1-2 players, 800 DSi Points): Save the land of Etheria using your legendary gem-matching abilities.
- 99Bullets (EnjoyUp Games, 1 player, 500 DSi Points): You have 99 lives, each one tied to one of your 99 bullets. Shoot judiciously.
- 3D Twist & Match (Sanuk Games, 1 player, 200 DSi Points): Rotate 3D objects to match silhouette images.
