Sploder

Make it yours

Every game is unique

Sploder isn't built around one kind of game. Top-down adventures, arena shooters, puzzle boxes, racing courses, dungeon crawlers, escape rooms, stealth missions — the same toolkit makes them all. You decide what your game feels like.

Twin-stick combat, classic arcade controls, or pure top-down navigation.
Adventure quests with locked doors, collectible keys, and multi-room worlds.
Puzzle boxes wired together with pressure pads, switches, and timers.
Survival runs with oxygen meters, lava floors, and burning hazards.

Level editor

Paint worlds out of pieces

Drop walls, doors, hazards, enemies, and items onto a tile grid. Stitch any number of rooms into a single world with portals, exits, and color-coded keys.

Brush, line, and flood-fill tools, plus copy / paste / rotate / flip selections.
Procedural generators: caves, dungeons, mazes, labyrinths, rivers, scatter, terrain.
Multi-scene worlds with portals, scene-to-scene teleporters, and locked colored doors.
Layered editing: floor, walls, items, AI, background — toggle each layer on or off.

Sprite editor

Pixel art, in the browser

Re-skin a single enemy or the entire game. Every entity gets up to five visual states (idle, walk, melee, hurt, death) with up to five animation frames each.

7×7 pixel canvas with a chunky retro palette and one-click palette swap.
Directional facing, animation playback, mask-mode pixels for diagonals.
Save your art as a sprite pack and share it as a single file.

SFX designer

Procedural sound on every event

Sploder generates sound effects in the browser — no audio uploads. Tune the parameters of every event, from footsteps to explosions, and they bake into a snappy, single-link game.

Sounds bind to events: hit, fire, pickup, jump, alert, explode, collect, click.
Per-entity overrides: give your boss a different roar than your grunt.
Single-shot, sustained, ambient, and spatial-attenuated playback modes.

Music composer

A sequencer, in the studio

Compose loops without leaving the browser. Multi-track step sequencer, instrument sculptors, BPM control, and a loop library you can pull from at any time.

16-step grid across up to 8 measures, with per-track sculptors for tone shaping.
Multiple synth tracks plus drums; each track gets its own filter, envelope, and vibrato.
Save and reuse loops across scenes — pick a different track per room.

Build together

Make games with friends, live

Share a link and your friends drop into your game with you. Paint scenes side by side, watch each other's cursors, and pile into the same room — every edit lands in real time.

One-click invite link — friends join straight from the URL, no extra account setup.
Live cursors and color-coded presence so you always know who's where.
Pause the room any time the host needs space to think, kick anyone who shouldn't be there.
Owner stays in charge of project-wide assets; friends help paint, place, and explore.

Rewind

Roll back any moment

A collab session keeps a rolling history of recent moments. Hit Rewind, scrub a video-style slider, and the world jumps to that snapshot instantly. Confirm to roll back, or cancel to keep going.

Live preview while you scrub: the canvas reflects the chosen moment without committing.
Auto-captured every few seconds — there's always something to rewind to.
Friend got carried away with the lava brush? One scrub puts the room back the way it was.
When the session ends, take one last look — review the final seconds before saving.

Free-for-All

A live arena in every game

Flip multiplayer on when you publish and your game becomes a live arena. Friends join by share link, the host hits Start, and the match runs for real — every hit, respawn, and victory settled by the same rules that govern solo play.

Up to 4 players in a Free-for-All match, all from the same share link — no install, no extra setup.
The match runs on a real server, not peer-to-peer — no rubberbanding, no cheating your score.
Live match feed, big defeat callouts, and a final scoreboard with the winner highlighted.
Host another round in a click — the lobby resets in place, your friends come along, no rejoin needed.

Share & remix

Publish, share, and remix

Hit Publish and you get a single URL anyone can play in the browser. Share the assets too and other players can fork your sprites, sounds, and music.

One-click publish to a public /g/your-game URL with auto-generated link previews.
Share-as-template: export any scene (or a whole project) as a starting kit other players can remix.
Built-in My Games library for everything you've published or saved.
