Charming but frustrating. The idea of this game is better than its execution. I would love to be a Ghostbusters Luigi, and the co-op is great in theory.

The game design and controls feel like relics of the GameCube era. Discovering how to damage many bosses and mini-bosses is an exercise in patience and experimentation that rarely feels rewarding.

The act of pointing Luigi at a target to shoot/blow/suck/grab is nothing short of torture. I understand the desire to keep the camera perspective as-is to retain that dollhouse graphical vibe, but they need to modernize controls atop that somehow. Maybe you could overlay a reticule on-screen and have Luigi automatically aim at it? I don't know.

The graphics and art direction are great, sound design is fantastic too.

But ultimately the combat is too hit-or-miss, and exploration feels nearly meaningless since the only things you can buy with money are more lives (the game isn't too hard, especially in co-op) or hints for... more meaningless items to gather?

Sometimes cracking the puzzles was fun, but other times you were left wondering why you should both.
