Out of line is a side-scrolling platform-hop puzzle game in which the protagonist San is taken over by a factory in his home, and giant iron claws and various ruthless machines wreak havoc on the once beautiful home. In order to uncover the secrets behind all this and save his homeland, San embarked on a journey of salvation with his special skill, throwing javelins.

In this work, the protagonist San is an uncompromising "javelin little prince", he has a magical javelin, not only can be recovered anytime and anywhere after throwing, but also can be stabd in any place that can be plunged after throwing, and can become a springboard to reach a high place. Therefore, the protagonist can reach many unattainable places with the help of javelins, which is one of the core settings of the game's gameplay, and it is also the most important setting. Throwing the javelin where it is needed, as a springboard, can reach the original place that cannot be reached, this technique will be used repeatedly in later games, which may not be particularly innovative in platform jumping games, but the actual game experience is very operational.
In addition, there are a large number of mechanical mechanisms controlled by gears in this game, and the levels formed by these organs are often impossible for us to pass directly. In this case, we can throw the javelin in the protagonist's hand to the twist between the gears and gears, jamming the gears so that they cannot continue to operate. In this way, the mechanical mechanisms that hinder our progress cannot continue to run because the gears are stuck, and we can pass unharmed. This design can be said to be both brainy and reasonable, very clever.
But the javelin is useful beyond that. In many scenarios there will be some switching devices, but these devices do not have a joystick. In this case, our protagonist can use these devices by inserting his own javelin into the device as a joystick. The role of the device is usually used to control the moving platforms in the scene, and these movable platforms can sometimes help the protagonist reach some places that cannot be directly reached, and sometimes it is used to help the protagonist's partners move, because some levels must be completed by the protagonist's partners.
Speaking of the protagonist's partner, I have to say that this is the finishing touch of this work. As a dystopian game, the protagonist of this game needs to challenge the layers of barriers, face a variety of cruel and complex tests, and often be powerless to be alone. Don't worry, though, as the levels and plot progress, there will be partners to help our protagonist. Although the player can not directly manipulate other characters other than the protagonist, but through the protagonist's actions in the scene, the player can quickly understand the behavior logic of the partner, so as to guide the partner's action through the operation of the protagonist, so that the partner can complete the action that the protagonist cannot complete, this way of solving the puzzle that does not allow the protagonist to directly participate is very interesting.
Many levels need the help of partners to pass, and we must also pay attention to when operating the protagonist, not only the protagonist can not die, the partner can not die, once the partner dies, the consequences and the protagonist die, will lead to the failure of the game. However, this game has a very user-friendly place - the setting of the auto-save point is very intimate, usually the player will automatically save after solving the current mechanism or after passing the current location, generally speaking, the player only needs to continue the game from the failure after failure, without repeating the game content that has been passed before.
"Beyond the Boundary" is a horizontal platform jump puzzle game, although the overall process is not very long, but the density of mechanisms and puzzles is very large, and the rhythm of the game is very tight. Although the game's plot does not have a verbal and written narrative, in the process of breaking through the level and solving the puzzle, the player will gradually understand the entire story in the process of interacting with the scene and the behavior of the partners, and the sense of immersion is very strong. Overall, this is a good game, and friends who like horizontal platform jumping gameplay or puzzle games can try it.
