"From the start I had planned to release it for PC and mobile phones, so there weren’t any particular difficulties. When developing a game, the graphics are always expensive to create, but once you start thinking about improving their quality there’s really no end to it, and I always struggle with where to draw the line. But since I started development on the mobile platform, which has hardware limitations, I knew what the minimum requirements were beforehand. From there I brushed things up for the PC version, and I think it was a really efficient way to develop. With the mobile version my goal was to make “the best shooting game ever for a mobile phone,” so I worked hard tuning it up."
