An iPhone app developer is donating to a nonprofit for each sale made, in what is believed to be a first.
For every sale of the $2.99 app during March and April the developer, GiantCrayon Games, will donate $1 to the ASPCA.
In the game, players arrange falling blocks to rescue animated kittens who are stuck in a Minnesota winter and win points. A video preview is on YouTube.
If only rescuing real kittens were that simple.
