spaceshmup

spaceshmup is a action game by Marek Olszewski, submitted to the js13kGames 2018 competition. Like every js13k entry, it was built from scratch in under 13 kilobytes — code, art and audio all included — a constraint that rewards focused, clever design. It was recognised in the 2018 competition.

We catalogue it because it represents the spirit of the size-limited game jam: a complete, playable experience distilled to its essence. Open it on the official js13k showcase to see what fits in 13KB. (This is a factual placeholder — a full review will follow.)

Most js13kGames entries use keyboard or mouse controls. Open spaceshmup on the official js13kGames page to read its in-game instructions, as controls vary per entry.

Generally: arrow keys or WASD for movement, the mouse for point-and-click titles, and space for primary actions. Many entries show their controls on a title screen. (This is a factual placeholder — specific controls will be documented in the full guide.)
