Blagger

Blagger is a single-screen platform game where you play as Roger the Dodger, a burglar on a mission to collect keys and crack safes. Each level presents a static screen filled with platforms, hazards, and scattered golden keys. Your goal is to collect all keys within a strict time limit, then reach the safe to advance. Blagger can walk left or right and jump in a fixed arc that cannot be altered once initiated. Not all platforms are safe: some crumble away after being stepped on, while others slide you in a particular direction. You will die if you touch cacti, moving enemies (cars, aliens, mad hatters, giant mouths), or fall from too great a height. Enemy movement follows fixed patterns, requiring precise timing and memorization. Points are awarded per key, plus a time bonus for completing the level quickly.
