Franky Lettuce is a simple puzzle platformer where you collect three drops sprinkled in a level before heading to the exit. You can get stuck a bit early on because of some badly colored platforms (grey platform on black background), but after that, the game is easy. All the levels fit on a single screen, so you can easily plan your route beforehand. There are no enemies, the only thing that can kill you is terrain. There's no real interaction with the world, most puzzles revolve around jumping to and from a new platform type.

Achievements are a bit interesting requiring you to perform an additional task (for instance not stepping on certain platforms), but you are only given a hint at what that task is. You get a notification at the exact moment when you fail the task, so even if you don't understand the clue right away you can figure it out through repeated failure. These are a bit hit and miss, with some later levels just giving you the achievement for completing the stage.

Franky Lettuce is a short mediocre puzzle platformer. While it does have some interesting mechanics in how it handles achievements, the game itself is incredibly safe and boring. With so many great options for the puzzle platformer genre (FEZ, Braid, Thomas Was Alone, Toki Tori), there's little point in playing this.
