A refreshing little game with blue-green as the main color. A game with the core gameplay of drawing with a ruler, involving conventional drawing, single ruler drawing, and single ruler drawing. The difficulty increases (slightly difficult), with tests of foundation, thinking, and even endurance.

About this game
This game, called 'Compass&Straightedge', is a geometric puzzle game with ruler and gauge drawing as its core. It is produced by ShaoJH and focuses on fun challenges in geometric drawing.
In terms of gameplay, it relies on six major tools: "point, line, circle, wipe, mark, and pass". Players need to determine the position with "point", connect two points with "line", and determine the radius of the circle center with "circle" according to the geometric requirements of each level (such as making equilateral triangles, drawing the common tangent of circles, making angle bisectors, etc.). With the help of these basic rules, they can complete the task and click "pass" to enter the next level. The operation logic follows traditional geometric drawing rules, and is both informative and informative.
In terms of content, the levels are designed around classic geometric problems: from making equilateral triangles on line segments and constructing equilateral triangles on concentric circles, to finding the four common tangents of two circles and making circles that are tangent to multiple known circles. The tasks cover the core scenarios of basic geometric drawing, which not only tests the understanding of geometric principles, but also exercises the rigor of drawing practice.
The artistic style follows the minimalist pixel style route: the interface is dominated by fresh blue-green tones, the tool buttons are simple block styles, and the geometric shapes are presented with clean lines without unnecessary decorative elements. It not only conforms to the texture of retro games, but also makes geometric shapes the visual core. It combines functionality and simplicity, and the overall atmosphere is relaxed and focused on the drawing itself.

More12 level have been removed due to persistent floating-point precision issues
The More12 level have been removed due to persistent floating-point precision issues.Given the unique nature of these levels, they involve extreme edge cases that demand extremely high precision, a problem I am currently unable to resolve.In addition, I have implemented more thorough lossless compression for the game build, which does not compromise the precision of the core game algorithms.Current file size: 3.54 MBRead full article on Community Announcements (ShaoJH)
