I work for Retro Army making Super Trench Attack! I worked previously in the industry for 14 years, for various companies. I also made Last of the patriots (free game) and The Old Man Game. I mainly dabble in Art/code/and design, but I'm trying to move into the business side of things now, must be showing my age. I also try to help younger developers get a start in the industry when and where possible.
Here I was testing the buddy character that follows you around, which never made it into Keiser's. It happens in development sometimes that good features can get lost or dropped. So it's important to play older versions sometimes to keep your games original direction intact.
