“I’d never played any video games until then, but in order to act as a director for this game project, I bought all video games available and some software. As this ‘Dee Dee PLANET’ was based on 8 bit games from the 80’s, I played the old Nintendo selectively. ‘Dee Dee PLANET’ is categorized as a shooting game, but almost all existing shooting games have lots of options which players can choose as they like. Players choose their weapons, vehicles and fields, and they upgrade their characters based on their score. This can be applied to other genres like car-racing, fighting and role-playing games.
This ‘Dee Dee PLANET’ is a kind of shooting game which shoots using a parabola, and is pastoral rather than speedy. It has a mathematical clearness by controlling the parabola with only two parameters – angle and shooting power. We set up a totally different theme apart from the offensiveness of other shooting games.
Players fight with their opponents operating their robots inside of three different zones – block zone, gel zone and liquid zone. Each zone is filled with different materials (gas, viscous material and liquid), different gravity and different resistance. There’s also difference in the power of each wheel as player’s feet and weapon. They have affinities between each zone. Players cannot choose those elements by themselves, they’re just given to them. It’s kind of an Oriental outlook on the world – ‘once a man comes into this world with his own body, he has to live out his life’. We included absurd events and developments in our first plan. Some of them were actually included in the game, and some were taken off from the specifications in the process.” [Quoted from shift.jp.org]
Dee Dee Planet was finished, but canceled due to a large networking bug.
