Wormax.io

This is an intense, competitive .io arcade game played in short, high-stakes sessions that can be interrupted at any time. While playable offline against bots, the core experience is online multiplayer, and progression is tied to acquiring upgrades and cosmetics, with some users reporting issues with lost progress and potentially unfair monetization. It's best suited for players who enjoy fast-paced, addictive gameplay and don't mind the potential for frustration with its progression systems.
