Spectrum Sprites

Two teams of six small elemental creatures stand on a randomly generated island and try to shove each other into the sea. That is the whole pitch. You have seen this game before. It usually needs a 4 GB download and a launcher that wants your email address. This one is 13 kilobytes and it wants nothing.

Everybody gets a signature move and a shared box of finite weapons. Ember sets things on fire, Tide floods, Grove grows terrain out of nothing, Volt forks lightning, Moon splits, Solar draws a line and deletes whatever is standing on it. Pick a shot, hold the mouse to charge, watch the little dotted arc, and let go. The arc is honest. If the shot goes into a hill, that was you.

The ground is real and it remembers. Every explosion carves the terrain, so a tidy hilltop becomes a smoking overhang three turns later, and the bright spectral outline redraws itself around whatever is left. There are caves under the surface. You can rope across a gap or blink through a wall into one, which is either clever positioning or a fast way to fall in the water, depending on your judgement.

Then round four happens and a narwhal shows up. The narwhal is not on your team. The narwhal is not on anyone's team. It has a guard bar, four attacks, and strong opinions about the tide, which keeps rising for the rest of the match until the low ground is gone and everyone is fighting over the same shrinking rock. It is the best part. Do not make it angry early.

Play it hotseat on one keyboard, or host an online game and send a four letter room code to one specific friend. Online runs on a deterministic lockstep simulation over the official js13kGames relay, which is a long way of saying both screens show the same narwhal doing the same thing at the same time, and neither of you gets to blame lag when you miss.

Built for js13kGames 2026. The whole thing, art and sound and netcode and that narwhal, is one HTML file under the 13,312 byte limit.
