This copy and its source

Built from the eduke32-wasm v0.2.4 source (commit 37b56ee) with Emscripten 6.0.5, with a few changes: online play and the Multiplayer menu entry are left out, the engine doesn't use JavaScript's eval (so the page can run under a strict security policy), saved games are kept in your browser, quitting offers to play again, and there are touch controls.

Complete source, the changes and the build scripts: github.com/AntAir267/duke3d-web. Upstream source: eduke32-wasm v0.2.4, mirrored at github.com/AntAir267/eduke32-wasm.

Default keys

Move	W A S D or the arrow keys
Fire	left mouse button or Right Ctrl
Open, use	E
Jump / crouch	Space / Left Ctrl (C toggles crouch)
Run	Shift (Caps Lock for always run)
Weapons	1 to 0, or the mouse wheel
Inventory	Enter uses it, [ and ] pick
Map	Tab
Save / load	F2 / F3, quick save F6, quick load F9
Menu	Esc (also lets go of the mouse)

These are EDuke32's modern defaults (plus the Up and Down arrows), so the 1996 help screens (F1) list different keys. Options > Controls changes them.

Touch screens

The left half of the screen is a move stick: put your thumb down anywhere there and slide (push to the edge to run). Drag on the right half to look around. FIRE shoots (drag on it to aim while firing); USE opens doors and switches, then JUMP, DUCK, KICK, WPN (next weapon) and ITEM (use the selected item). MAP and MENU are at the side. In menus, use the arrows with OK and BACK. Pressing a real key hides the touch controls.
