Cosmos 404

Cosmos 404 is a fast-paced space runner where you sprint around tiny, randomly generated planets. Each new planet looks different from the last, with its own colors and landscapes. As you race along the surface, you collect coins scattered along your path while hostile aliens try to stop you. Bonuses help you survive longer: a speed boost makes your character run faster, and a magnet power-up automatically pulls in nearby coins. The visuals use a low-poly, angular style as your character runs in a loop around a small planet, with the track closing in on itself very quickly.

How to play?

You control your running direction with the arrow keys or swipes. Coins sit right on your path, so just run through them to collect them and increase your coin counter. Enemies appear on the planet, some crawling toward you and others standing still. If you collide with an alien, the run ends immediately, so you need to jump over them or run around them. Since the planet is small and circular, enemies can come up from behind, so always watch what is happening around you.

If you see a speed bonus, grab it so your character moves faster for a short time. This makes it easier to dodge enemies and pick up more coins. The magnet bonus attracts coins from a distance, so you do not have to step on them exactly to collect them. The longer you stay alive, the more enemies appear. The planet gradually fills with aliens, and you have less and less room to move.

After you have collected enough coins, open the shop between runs and buy access to new planets, such as ice, sand, or lava worlds. The look of the planet changes, but the core gameplay stays the same. As in any endless runner game, it is important to keep your distance from enemies, grab bonuses in time, and save up coins to unlock all planets. Try to set new survival records and collect as many coins as possible in each run.
