Crux

Crux was started in 1984 by Orca's software team (which included popular Toaplan programmer and composer Tatsuya Uemura) after that company went bankrupt and was thrown out of its building. After doing Gyrodine, Crux ran into financial difficulties and would eventually go bankrupt as well. With such uncertainty, the chief programmer on Gyrodine and two others left for Toa Kikaku and started a software division (which became Toaplan). Uemura was invited over, but did not leave until after he finished working on Repulse.

It is not known what finally happened to Crux, and Uemura does not specify on his homepage when exactly it went bankrupt. But it is clear that the remaining team worked on the other games listed below. Was this still Crux? Did Crux crawl out of bankruptcy? Did this team regroup as a new company?
