Keron Army Soldier "Keroro" created a neat tumblr account based upon answering questions about the Keroro Platoon. Heres the link:

Ask him some questions!

We have made quite some progress in our efforts to put Keroro Pang Pang on steam. The Change.org petition now has 250 supporters, and we have found out a lot about the game. We have figured out that Scaleform, a vector graphics rendering software company which is involved with many games such as Skyrim and Counter Strike, was involved with the Keroro Pang Pang project in 2008. From this information we deduced that the Korean-only game was developed by Nstorm and published by Goorm in 2008. We are looking for people who either know Korean or know anything about these 2 companies. If you find anything post a message on the discussions board or message me and [LLE]Keroro Knight . Here is the game's website, for those of you that can read Korean. Reading it might tell you a lot about the game. If you're willing to write an article about what you find, please do so on the discussions board. Thank you.
