Hollow Fly is an action-adventure game that challenges you to explore maze-like levels, avoid dangers, and gather every key before you can open the exit portal. Across three labyrinthine worlds, you will encounter enemies and hazards while making your way toward the light. Careful movement and smart use of your sonar beam can help you reach the next level.
How to play Hollow Fly
Your main objective in each level is to collect all of its keys. Once you have gathered them, look for the portal that leads onward. Since the route is filled with enemies and dangers, it is useful to explore methodically rather than rushing through unfamiliar areas.
- Move: Use the WASD keys or the arrow keys.
- Fire: Press X or the space bar to use your sonar beam.
Choose whichever movement keys feel most comfortable, and keep the fire control easy to reach. In a maze, pausing briefly to check your surroundings can help you avoid moving into a threat before you have a chance to respond.
Use the sonar beam and collect bonuses
Your sonar beam is your main way to defeat opponents. Use it when enemies obstruct your route, and stay alert for hazards as you move through each area. The game also includes bonuses that can improve your speed, firing power, or health. These boosts can make progress easier, so collect them when you find them.
There is an important trade-off: losing a life also removes all the bonuses you have collected. As a result, it can be worth prioritizing cautious movement when you are carrying several boosts. Avoid unnecessary encounters where possible, and use your beam to deal with opponents that stand in your way.
Explore the three labyrinthine worlds
Hollow Fly takes place across three worlds designed like labyrinths. Each level requires you to balance exploration with survival: keys are essential for opening the portal, but enemies and hazards can make reaching them more difficult. Keep track of areas you have already explored so you can focus on finding any remaining keys instead of repeatedly covering the same ground.
If a route seems dangerous, consider whether you can approach it from another direction. Staying aware of your health and current bonuses can also help you decide when to proceed carefully and when to move more quickly.
Hollow Fly: quick strategy summary
To make steady progress in Hollow Fly, learn the controls, search each level for every key, and use the sonar beam against enemies. Collect speed, firing-power, and health bonuses, but remember that they are lost when you lose a life. A measured approach through the three maze-like worlds can help you reach each portal and continue your adventure.
