Entropy
Entropy is a mass multiplayer online arena built on a beautifully simple loop: collect food, level up, get stronger, repeat — while everyone else on the map is doing the same, and only the leaderboard remembers who did it best. The game was developed by two friends in high school, and it wears its simplicity proudly.
How to Play
Roam the arena collecting food to gain levels. Each level makes you more powerful and more dangerous to smaller players — and juicier prey for bigger ones. The food chain is the whole game: know your place in it at every moment, and climb.
Controls
Move: Mouse / WASD
Action: Left mouse button
Simple to Play, Hard to Quit
Entropy belongs to the classic school of io games: zero tutorial, instant restart, and progress you can feel minute to minute. Death costs you your run, which makes every risky bite of food near a bigger player a genuine decision.
Tips
Farm the quiet edges early; the center belongs to high levels
Always know where the nearest bigger player is
Deny food to rivals your size — starving them is as good as fighting
After a big player dies, their zone is briefly free real estate: move in
Short escape routes beat greedy detours; live to eat again
