A micro-sized score-chaser that asks one question and nothing else: how long can you stay alive when the geometry wants you dead?

I have a soft spot for the smallest possible statement a game can make, and Fission from solo developer kashW makes about the smallest one I have encountered on Steam. You guide a dark cube along a forward-scrolling 3D lane, shattering rotating golden cubes for points while weaving around gray obstacle shapes that kill you on contact. One hit, full restart. That is the entire contract, written in about thirty seconds of play. The loop is genuinely stripped to bone. There are no upgrades, no branching paths, no lives system to soften the blow. What keeps you going is the speed curve: the game quietly accelerates as your score climbs, so the first handful of points feel almost meditative and the later stretch turns twitchy in a way that earns the restart rather than just punishing sloppiness. The golden cubes spin as they sit in the lane, which sounds cosmetic but actually gives you a small timing cue to read before you commit to a path. It is a tiny mechanical grace note that I appreciated. The minimalist 3D aesthetic is clean without being ambitious. Dark background, high-contrast golden targets, gray hazards that read clearly against everything else. There is no visual noise to blame for a failed run, which is the right call for this kind of reflex game. The music, described by the developer as pleasant, does what it needs to: it sits underneath the action without demanding attention and adds a quiet ambient quality that keeps the mood from feeling sterile. Honesty first though: Fission is a proof-of-concept sized game, not a full release in any traditional sense. There are four Steam achievements and a score to chase. Community posts have noted that a post-launch update changed the density of golden cubes on screen, making those achievements meaningfully harder to unlock than the trailer implied. If achievements are your primary motivation, go in with eyes open. For everyone else, the loop either hooks you or it does not, and you will know within two minutes which camp you fall into. This sits comfortably in the same breath as free mobile runners and old Flash score-chasers. If you approach it as a palate cleanser between heavier games rather than a destination, Fission delivers exactly what it promises. The craft is modest, the ambition is small, and within those limits it is honest. Kai, Scout Team

GamerScout Verdict

Best for players who want a two-minute reflex reset between sessions, not a game they will think about tomorrow.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
