I just found this game that looks like pure fun. Flush the Goldfish a remixing sort of game, with many diffrent playing mode and a reduced input-mechanic. The A button changes the behaviour of the player in every room, like jumping, crawling, avoiding etc. Each screen is simple, filled with colorful pixelstyle-graphics. The game has casual upfront music and soundeffects. There is a in-depth-review – well written – avaiable at 4 Color Rebellion.
Flush the Goldfish is available for Nintendo DSiWare made by Goodbye Galaxy Games. Go for it!
