The project originally went under the working title "Propeller Wars" early in development, before being renamed as "Garden of Progear" and was first envisioned as a vertical-scrolling shooter but Capcom remarked that the name was "too highbrow" and one of the higher-ups at CAVE told the team during their presentation pitch that the project should be a horizontal-scrolling shooter instead, with Ikeda revealing in a 2010 interview that the project was also intended to be their last release as the company was considering leaving the arcade market due to several factors at the time. The team decided to make bullet dodging and enemy destruction its main focus, while adapting the company's shoot 'em up gameplay style in a horizontal format but the project would go through a problematic development cycle until it was released. Both Ikeda and Inoue stated that working with the CP System II platform, which marked the second time CAVE made use of an external arcade board, proved to be difficult as the hardware was underpowered compared to the previous board used for "Guwange", with designers using a limited number of colors to remake drawings created in Photoshop.
