黑板风坐标系跳跃游戏，适用于 Mac App Store 上架元数据和隐私说明
《Godot Cartesian》是一款在黑板上运行的数学跳跃游戏：你从原点出发，靠蓄力抛物线与坐标系上的几何障碍做出精准落点，把曲线和横轴围成的面积转化成分数。它支持离线游玩，适合 Mac App Store 上架。
《Godot Cartesian》是一款把数学课搬到黑板上的跳跃游戏。
整个世界是一张画在黑板上的平面直角坐标系：纯黑板面、白色粉笔线，你就是那个从原点出发的线条小人。
【怎么玩】
• 按住蓄力，松手起跳——每一次跳跃都是一条抛物线
• 曲线与横轴围成的面积实时计分：跳得越高越远，圈住的分数越多
• 蓄力时预测曲线与预计得分会实时“生长”，看着积分上涨再决定何时松手
【障碍与规则】
• 20 个关卡顺序解锁，12 种几何形态逐步登场：长方体、线段、三角形、平行四边形、圆形、椭圆、抛物线、双曲线、正弦、余弦、对数、倒数
• 只有夹角超过 75° 的致命尖角才会让你出局，所有致命陡面都有醒目的交叉纹理提示
• 缓坡可以直接走上去，光滑曲线可以踩着滑行——数学就是你的地形
• 落在障碍顶部可以继续起跳，撞上悬浮线段会被稳稳弹回
【特色】
• 面积即分数：把“积分”变成看得见的手感
• 黑板粉笔画风：纯黑背景与白色线条，越玩越像老师的板书
• 每关记录最高分，通关即解锁下一关，进度自动保存，随时离线畅玩
从长方体起步，一路跳到倒数曲线——这块黑板，等你来画。
Godot Cartesian is a jumping game drawn on a chalkboard.
The whole world is a Cartesian coordinate system in white chalk on black slate — and you are a little stick figure starting from the origin.
HOW TO PLAY
• Hold to charge, release to jump — every jump is a parabola
• The area enclosed by your curve and the x-axis is your score in real time
• While charging, a ghost curve and its predicted area grow live: watch the integral climb, then let go
OBSTACLES & RULES
• 20 levels unlocked one by one, with 12 geometry shapes joining progressively: rectangles, segments, triangles, parallelograms, circles, ellipses, parabolas, hyperbolas, sine, cosine, logarithmic and reciprocal curves
• Only sharp corners steeper than 75° are lethal — every deadly face is clearly textured; smooth curves are always safe to ride
• Walk straight up gentle slopes, launch off curved ones, bounce off floating lines, and keep jumping from obstacle tops
FEATURES
• Area is score: calculus you can feel
• Chalkboard art: pure black, white lines, hand-drawn charm
• Best score per level, sequential unlocks, auto-saved progress, fully offline
Start from a box, finish on a reciprocal curve. The blackboard awaits.
