You need to Make sure they understand every mechanic of the game.

你得确保玩家能完全掌握游戏的各种玩法
So every level in the first chapter

所以第一章里的每一关
needs that have some example

都需要通过一些示例
forcing the player to do something in order to beat the level

强迫玩家进行一些必须的操作才能过这一关
that they will need further in the game.

而这些操作正是后面的游戏里所必需的
So there is a level, I think it's level three,

比如说有这么一关大概是第三关
there's just a gap.

就只有一个大裂口
The only way to get over that gap

想跳过裂口的唯一办法
is to hold on 'run' and 'jump'

就是按住移动键然后按一下跳跃键
You can't get it any other way.

除此之外没别的办法
You can't just keep jumping around.

你就算一直跳也没用
You won't jump far enough.

因为只按跳没法跳那么远
