Something feels off almost immediately. The scenery looks familiar enough to trigger old Mario instincts, yet those instincts keep getting you into trouble. Luigi's route becomes increasingly uneasy as ordinary enemies and obstacles stop behaving the way you expect. The controls are hardly the problem; it is the sudden changes that keep you second-guessing every step.
Fans of Mario.EXE-style horror will recognise the flavour, but there is enough stage trickery to keep it from feeling like a straight retread. The full version is already unlocked, with the complete stages and hidden content available from the start. A brisk little horror platformer for anyone who likes their childhood nostalgia with a decidedly crooked grin.
