For a limited time, iOS game Last Fish is free. The game is described on the developer’s site as a “stylish black and white action game about the survival of a tiny fish in toxic water filled with goo.”
The game’s 45 levels are played with tilt-based movements and the game has a great aesthetic. Critics seems to agree, with plenty of praise for the game’s simple fun. It was already cheap, but now you can get it for free so what are you waiting for?
Here’s a trailer to whet your appetite:
