IT REALLY HERTZ
Presenting Jerms first Game Jam game (and first game):
IT REALLY HERTZ
A physics-based puzzle platformer where your world is made of waves!
About the Game
Welcome to the world of HERTZ, where sound wave physics become reality. Your platforms aren't solid! They're sine waves that you can manipulate using the principles of wave interference (audio masking!!). Master destructive and constructive interference to solve increasingly complex puzzles!
Created in less than 72 hours for Winter MelonJam 2025 (theme: "mask"), this game explores the concept of audio masking: when sound waves interfere with each other, either canceling out or amplifying.
How to Play
MOVEMENT:
- A/D or Arrow Keys - Move
- SPACE - Jump
- MOUSE - Click and drag waves
MECHANICS:
- Inverse Waves (cyan) - Use destructive interference to cancel out platforms
- Amplify Waves (orange) - Use constructive interference to make platforms bigger (stackable!)
- Square Waves - Moving platforms that push you along
OBJECTIVES:
- Collect the KEY
- Reach the PORTAL
- Avoid spikes and falling!
The Science Behind It
Audio masking occurs when one sound makes another sound harder to hear. When sound waves overlap, they interfere:
- Destructive interference (opposite phases) = waves cancel out
- Constructive interference (same phase) = waves amplify
This is the same physics behind noise-canceling headphones! In HERTZ, you manipulate wave platforms using these exact principles.
Features
- Physics-based wave manipulation puzzles
- Unique visual style with animated backgrounds
- Speedrun timer for competitive play
- Death counter to track your progress
- Original soundtrack
- Night mode toggle for accessibility
- Smooth platforming with coyote time and jump buffering
Tips
- Stack multiple amplify waves for extra-tall platforms
- Use inverse waves strategically—sometimes less platform is better
- Watch out for square wave walls—they'll push you!
- Try for a perfect run with zero deaths!

Love the music and game feel! :D sprite looks cute too
This is amazing, genuinenly! Love the idea, the artstyle, the music. Waves all the way! Thank you for making this. 9/10, would pay for this if some more content was added
This game is very cool, but it has no masks wich is gamejams theme
Thank you so much! The game is about masking waves!
ooh ok
