Choke on My Groundhog, You Robots is a new monthly experimental game by Petri Purho, where players will engage waves after waves of enemy robots in a fight for their survival. This Assembly 2008 Gamedev entry employs a certain time travel gimmick to make subsequent attempts at each level a little easier.

There are only four stages to play in total.
