Yoyogames Sandbox - The Clown and the Secretaries
This one is a puzzle game with decent gameplay, but the art and animation really sells it. For such tiny sprites, the characters explode with personality (then literally explode with helium). I went in expecting it to be a tedious puzzle game, and was surprised by the variety of my long-legged nemeses. It's also interesting in that it abandons the scuba diver motif and replaces it with...two things that absolutely don't go together. Unless the plot involves an office party gone awry.
Okay, I'm done tormenting you with this weirdness. Strangely enough, I find myself recommending these games. They're bizarre, but some of them manage to be pretty fun despite the subject matter. As a sexual deviant, it's not my cup of tea; but as an artist, I'm quite satisfied.
