The Real Ghostbusters on Game Boy looks cute for about five minutes, then it starts asking you to read rooms properly, manage risk, and stop jumping into enemies like Peter owes them money.

This page covers the basic controls, what each item does, and the habits that make the full 51-floor run much less painful.

Controls

  • D-pad: move Peter
  • A: jump and confirm menu choices
  • B: fire the proton pack
  • Start / Select: open the menu

That is the whole move list. The challenge is not complexity. It is making clean decisions with simple tools.

What every item does

  • Stars: collect the full set on each floor to make the exit key appear.
  • Arrow, circle, X, and door keys: open matching gates, shortcuts, or the stage exit.
  • Bombs: drop them on the ground and let enemies walk into them.
  • Hearts: refill health.
  • Peter icons: extra lives.
  • Potions: give Peter a short stretch where he can tear through enemies safely.
  • Clocks: add 50 seconds to the timer.

Best beginner habits

  • Look for the easiest stars first so the room opens up before you take riskier jumps.
  • Figure out which key you need before you start breaking random blocks.
  • Notice where the nearest heart is. You do not want to discover it one hit too late.
  • Use bombs where patrol routes are tight and annoying.
  • Leave the stage as soon as the door key appears. There is no prize for sightseeing.

When to use bombs

Bombs are not rare enough to hoard forever, but they are too useful to waste on a lazy impulse.

The best places to use them are narrow ledges, ladder landings, and short hallways where an enemy keeps reversing direction and eating your time. If an enemy is easy to jump over, save the bomb.

How to handle short-timer floors

Several late stages hand you a nasty clock and dare you to panic. Do not.

  • commit to one route
  • skip unnecessary fights
  • grab hidden clocks when the route depends on them
  • keep moving, especially on floors like Stage 20, Stage 23, and Stage 38

These stages usually feel worse when you hesitate than when you play aggressively.

How warp doors fit into the run

Some warp doors are just shortcuts. Some are basically the answer key.

If a floor keeps feeling too long, there is a good chance the real route depends on a warp, a hidden wall, or a drop that looks wrong at first. The game loves that kind of trick.

The easiest mistakes to fix

  • breaking blocks you still needed as platforms
  • taking damage for a star that could have waited
  • using a bomb in an open area instead of saving it for a choke point
  • forgetting that clocks and hearts are often hidden inside blocks
  • treating the last stage like a normal floor instead of a setup puzzle

What to remember before Stage 51

The final fight is more of a trap puzzle than a straight boss battle. Save your calm for that stage. Once you understand how to box the boss in with regenerating blocks, the ending is much less scary than the climb to get there.
