Voidcall
A real-time strategy game in 13KB of JavaScript and WebGL. Command units, capture resources, and conquer the map.
About Voidcall
You start with a handful of units and a fog-covered map. From there, it's a race to capture resource nodes, build your forces, and push the enemy off the board before they do the same to you. Voidcall is a strategy game that strips real-time tactics down to their essentials — movement, positioning, and resource control — with no fluff in the way.
What makes it quietly remarkable is the constraint behind it: the entire game runs in roughly 13 kilobytes of JavaScript and WebGL. That's smaller than most images on a webpage, yet it delivers a complete RTS loop with smooth rendering and responsive unit control. If you enjoy this kind of technical craft, HexGL Racing is another WebGL-powered title worth a look.
Voidcall plays entirely in the browser with mouse controls, so no installation or account is needed — it loads in seconds and runs well on a laptop or desktop with a dedicated mouse.

A sweet physics drop-merge game where you launch candies upward into a growing pile. Match identical treats to merge them into bigger, more delicious sweets — and watch for special drops that clear whole columns or blast the board. Keep the pile from overflowing before the shop closes!
