is a beat 'em up from Rectangle, developer of the Raiders Sphere series. Your character's moves are limited to punches and a mid-air kick. A combo can be executed by tapping the Z key repeatly.
Backgrounds are bland but serviceable. The subway level is pretty interesting although much of what the screenshots promised do not appear in the trial version.
