The Binding of Isaac

The Binding of Isaac (original Flash version) is a top-down bullet hell roguelike dungeon crawler created by Edmund McMillen and Florian Himsl, released on September 29, 2011. The Wrath of the Lamb DLC requires this base game to run. Story: Isaac’s mother believes she hears the voice of God ordering her to sacrifice her son to prove her faith. Isaac flees into the basement of their house. He fights grotesque monsters and confronts his fears inside procedurally generated dungeons until he faces his mother, the final boss. Core gameplay - **Permadeath**: When your character dies, the entire run resets. Every new run generates a completely different dungeon layout. - Controls: WASD for movement. Use mouse to aim and fire tears as projectiles. Bombs destroy obstacles and hurt enemies. Keys unlock treasure chests and doors. - Hundreds of passive and active items can be picked up. Items have powerful synergies, changing tear effects, health, speed and character visuals. - Isaac is the only starting character. More playable characters (Magdalene, Cain, Judas, Eve, Samson) are unlocked by beating the game. - Room types include combat rooms, shops, treasure rooms, secret rooms and Devil Rooms. You must defeat all enemies to unlock the exit door. The base game features four main chapters across 8 floors, over 50 enemy types, more than 20 bosses and multiple endings. The original release was built on Flash. Since Flash was discontinued, there is no official browser version. Any web playable builds online are unofficial fan ports. A full remake, The Binding of Isaac: Rebirth, was released in 2014 with massive content expansion.

These games get the keyboard directly — the controls are whatever the game itself defines, usually in its own help or options screen. Some games show on-screen buttons on phones.
