I’m Marcus Körner (online: atla). I’ve been building games since I was 16 — roughly since 2000, about 26 years of hobby gamedev and side projects.

By day I’m a software engineering manager. By night (and weekends) I ship MUDs, arcade toys, and small experiments — many of them Android titles earlier on, later web and multiplayer.

This site (Leihwelt) is the quiet catalogue of those hobby projects — not the arcade itself.
