Programming.io

An agar.io-style arena where the blob you drive is a programming language. Eat code, grow, and try not to get executed by something bigger.

Pick a family, switch inside it

select 1 language family at start: SCRIPTED , MANAGED , NATIVE and  FUNCTIONAL then switch between it's languages in on-going game

Different languages, different abilities

• PYTHON · IMPORT * — drags every scrap of code around straight to you like magnet.
• PHP · GLOBAL SCOPE — pins every rival around you in place, and blocks their ability too.
• RUBY · MONKEY PATCH — leaves a trap behind. Whoever walks into it feeds you.

• JAVA · CHECKED EXCEPTION — stores up every hit you take, then unloads it all at once on the next rival you touch.
• DART · AOT DART — throws a dart that rips size off whoever it hits and give that mass back. but if you miss then you lose some of your own mass
• KOTLIN · INTEROP — steals a nearby rival’s ability and keeps it on a second button.

• GO · GOROUTINE FAN-OUT — two copies of you that hunt and eat on their own. Whatever they gain comes back.

• C++ · HEAP ALLOC — drops half your size where you stand. Only you can see it, only you can pick it up later.
• ZIG · ALLOCATOR — rips size off whoever you touch, but steal again quickly or it drains away.

• OCAML · PERSISTENT VALUE — save yourself as you are now. Press again to snap back to it, even after being eaten.
• and many more...

The arena fights back

The board is filled with hazards : bugs, infinite loops, memory leaks, race conditions, stack overflows and merge conflicts. Each family is immune to some of them but not all. 

Three modes

Campaign (single player) — drop into an arena that keeps spawning rivals, climb the board, and take out the last one standing.

Sandbox (single player) — choose your language, choose exactly which rivals stand on the board, and how arena fights back.

Versus (up to 4 players) — host an arena, share the room code, and fight your friends with the language you brought.
