## What is Godot Cartesian?

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.
