Rolls elements of Sonic, Metroid, and Galaga into one game
At first glance, I wasn't entirely sure about Glorkbot's Mini Adventure -- but then you notice the inspirations, and it all comes together in a nice little package. This is the result of Pixeljam teaming up with comic book artist James Kochalka. They are targeting Windows, Linux, and Mac at the tail end of this year, so the wait shouldn't be too long.
Previously, there was a Kickstarter campaign for a videogame called Glorkian Warrior that was successful enough to be funded. That project has been put on hold for the time being, hence this smaller title. It's made up of one level (albeit a large one) that can take minutes or hours to complete depending on how much you explore. Looks promising.
