Spaceship Explorer was cruising amongst the universe. Suddenly a once invisible ward appears, but it was too late to turn back: the spaceship was devoured by the ward, and you, as the sole cosmonaut on it, went unconscious. The spaceship is composed of five rooms: Lab, Main Console, Power Control, Living Roon and Storehouse. The lab is the first to be affected by the erosion. Luckily, some prototype gadgets brought on the ship were surprisingly able to offset the erosion of the outward, but only for those under a certain intension. Some devices in the lab can be used to upgrade, compose, or even produce new gadgets from existing materials; but the only available source is those in the living room, the remainder of the memories from the life before. To leave in peace, or strive desperately to live... But all these forces they are too strong to counterattack... In the end, everything annihilates - leaving only you and yourself. The world eroded is not so horrifying but even more attractive and colorful than the original one. Are all the efforts worthwhile? Will those decisions ever be regrettable...?

• 3D Motion - simulation of that in a spaceship

• Strategy - to hold back mist

• Tension - Meaning or life?

Sojourn is similar to tower defense: After running into the ward, the intension of the erosion will be expressed in terms of saturation of color (the ward will be displayed in purple, and higher saturation implies more intensive erosion). The player needs to place and adjust the gadgets properly so that the erosion could be mitigated; or even abandon several rooms in order to save the rest. The core technique of producing these gadgets are located in the lab, using which most common objects could be turned into defending gadgets. However, the techniques are locked in some obscured places in the lab, which may take some efforts and puzzle solving to be recovered. A choice needs to be made whether to save the left memories or to take the best approach to survive. There are three phases of the game. The first phase will be quite peace, but not last long: players are given time to walk around, to become familiar with the environment (the spaceship) and figure out the effect of the gadget. The second phase will be defense-abandon ones, where the erosion becomes considerablely intensive, but still can be mitigated; abandoning some rooms may be reqired in tbis phase. The third phase will be one where abandonments are musts, and the erosion will be so strong that it's hard to mitigate; and the resulting desperation and erosion returns to the end of the story.

A exciting while interesting game experience will be obtained when the player actively interact with the environment and tries his best to stop the erosion. The player will not only be inspired by the philosophy relating to the relationship between the grand universe and ourselves but also enjoy the exploring process of the game.
