The Browsing of Isaac

The Browsing of Isaac runs The Binding of Isaac: Repentance+ in a browser tab. It is the game's Windows code recompiled to WebAssembly, not a remake or an emulator, so items, synergies and bugs work as they do on PC.

How to play

• Keyboard: WASD to move, arrow keys to shoot, Space for the active item, Q for a card or pill, E for a bomb, Tab for the map, F for fullscreen.
• Phone: touch the game directly, left thumb to move and right thumb to shoot. There are no extra buttons on screen.
• Controller: plug it in, press any button, and start the run with it. It uses the Xbox layout, with analog sticks and rumble.

What you need

Nothing to install or upload. Use Chrome, Edge or another Chromium browser, on desktop or Android.

Good to know

• Saves stay in your browser. EDIT FILE on the file select screen exports or imports them, including a .dat save from PC.
• Steam Workshop mods run here too: open the MODS screen and use MOD BROWSER.
