Blek vs Chalk

Blek is a 2013 puzzle video game for iOS and Android where you draw a snakelike black line that repeats its shape and velocity across the screen. The line erases colored dots while avoiding black obstacles, turning simple gestures into a rhythmic challenge. Its minimalist design, ambient soundtrack, and excerpts of poet Erin Gee create a meditative experience inspired by Japanese calligraphy and the Bauhaus. Developed by the Kunabi Brother team, Blek earned a 2014 Apple Design Award and sold over one million copies.

Chalk is an indie arcade action game where you wield a virtual piece of chalk to draw lines across shapes, destroying them and turning the tide of battle. The simple yet addictive mechanic lets you reflect enemy bullets and bounce objects back at massive boss foes, creating fast‑paced, strategic fun. Designed for single‑player on PC, Chalk offers a retro‑style chalkboard aesthetic combined with modern physics, delivering a unique twist on classic arcade shooters. Its concise levels and intuitive controls make it easy to pick up, yet mastering the line‑drawing tactics provides a deep, rewarding challenge.
