How Irenaverse works

A guided path from your very first line of code to a game you made yourself — one small idea at a time.

snake.irene

# Steer the snake. Eat the gems, don't bite yourself.
snake = sprite("snake", 400, 300)
gem   = sprite("gem",   100, 100)
dx    = 20
dy    = 0
score = 0

on key_down "left":
    dx = -20
    dy = 0

every 120:
    snake.x = snake.x + dx
    snake.y = snake.y + dy
    text("Score: " + to_text(score), 20, 30)

# Spawn enemies that drift toward the snake.
fn spawn_enemy():
    e = sprite("raccoon", random(0, 760), 0)
    e.speed = 2
    return e

enemies = []

every 2000:
    append(enemies, spawn_enemy())

# Little helpers I keep handy.
fn clamp(value, low, high):
    if value < low:
        return low
    if value > high:
        return high
    return value

Score: 4 running

Ren

why doesn't my snake move?

Look at the every block — what changes snake.x there? Try logging dx after each key — is it what you expect?

Ren · ask anything

The editor: file tabs across the top, your code on the left, your game in the middle, your buddy on the right. Click a tab to peek at the other files.

Lessons that build on each other

Start with moving a dog across the screen. Each lesson adds exactly one new idea — keys, loops, variables, lists — so nothing ever feels like a wall. Finish one and the next unlocks.

Write real Irene code

Irene is a kid-friendly language that looks and feels like Python. The editor highlights what you type, autocompletes builtins, and explains any word when you hover it.

Press Run, play your game

Your code runs live on a canvas. Sprites move, keys respond, sounds play, the score ticks up. Change a number, run again, see what happens — that loop is where the learning lives.

Ren, your coding buddy

Ren lives in the chat next to your game. Hints first by default — she'll point at the line and ask what you'd try. Say "show me" for the code, or "walk me through it" when you want a step-by-step plan for something specific like "add an enemy". Ren only knows the concepts you've already unlocked, so help always fits where you are.

Ren

why doesn't my dog move?

Have a look at line 4 — what should dog.x be on each tick? Right now it's just sitting at the same number.

A hint, not the answer — that's how Ren helps by default. Say "show me" when you want the code.

Show a friend

When you've built something you're proud of, press Publish. You get a play link to send to a friend in your circle — they play it in their browser, leave a (safety-checked) comment, or remix it into their own account. Edit freely afterwards; friends only see what you published.

They'll see the snapshot you just published. Edit freely; your changes stay private until you Update.

One link. Only people you trust can open it.

The Sprite Studio — draw a character, give it animation frames, and use it in your game by name.

Draw your own sprites

A pixel studio with frames and onion-skinning. Paint a character, animate it, and use it in your game by name.

Add music

One line loops a chiptune soundtrack under the game — dozens of tunes, swappable on a scene change.

That's the whole loop.

Write, run, play, ask, share. Repeat until you've built something a friend wants to remix.
