In theme, and to a degree in gameplay, Choke On My Groundhog, You Bastard Robots (um, COMGYBR?) is an homage to Robotron. Robots have taken over the world, and you're going to take them on single-handed; there's no "last human family" to save, and shots aren't constrained to the four cardinal directions (thankfully -- WASD to move, aim with the mouse). Instead, there's time travel -- another recent indie game playing with that particular motif.
It's a straightforward shooter, with robots of increasing power entering from the four sides of the window, while you dodge and blast them; the gimmick is that when you die, you press the space bar to "travel in time," and the level restarts from the beginning -- with your previous self in play, and shooting as you did before you died. If there's a limit to the number of selves in play, I haven't found it.
This is interesting because it inverts one of the common tropes of the arcade shooter: just as more and more enemies show up as the game progresses, more and more yous show up as the game progresses. Indeed, you start to notice that in the early moments of the level, the bots get obliterated quickly, because so many folks are blasting away.
There are, of course, some paradoxes; an older you still dies even if the bot that got him was already killed, but hey, that's just how time travel works, apparently. Only the pasts of the enemies can be changed.
Graphics are reminiscent of Sketch Warriors -- the look is that of marginal doodles from a high-schooler's notebook. Another fine quickie from Petri Purho.
