Game description
A wave-interference arcade game where you emit expanding circles, trigger explosions at wave intersections, and try to survive the alien invasion.

Theme interpretation
The theme “WAVE” is interpreted through an interference system of expanding energy circles. Waves emitted from two antennas intersect dynamically, and those intersections become points where the player can trigger explosions. Timing and managing wave patterns is the core gameplay mechanic.

So fresh idea! With a bit of polish and level/abilities development could pretty good sellable game (for mobiles probably?) Nice job!

Thank you so much!

Yes, I'm trying to turn it into a "real" game. I'm working on it these days, even though I don't have much time to dedicate.

I also think it could work on mobile (I've already done a build and I can confirm it works very well), but I think it could also work on PC as a "fill-in-the-blank" game.

This is a very interesting and original mechanic. Great work!

I would like to see some expansion and iteration upon this idea. I was excited to see large explosions causing “back draft” waves, but wasn’t able to ever really utilize them well. Would love to see more chain reaction stuff / iteration on this interesting concept.

Nice work, continue to grow and challenge yourself!

This is a good game.

But it is a bit difficult in the first time, but after that, it became fun.

I liked the idea and execution of this game. It's a very original mechanic, using the intersections of the signals to target enemies is something I've never seen the like of.

You found an original take on the theme and made a solid little game around that. Well done!

I kinda struggled with the actual gameplay. I think my highest score was only 420 and I didn't survive for more than a few minutes at the most. It's very punishing and feels like it's almost impossible to get the intersections to land close to either of the antennas. Obviously, it's a skill issue on my part, but I also didn't feel too invested in exploring the game for more than 15 minutes.

The game would've benefitted if there was a slower ramp in the enemy spawn rate and if there maybe was some additional mechanic that would make aiming easier.

Visually, it's a clean, no frills game and the graphics definitely don't put the game to a shame. The audio was okay as well.

Overall, it's a good entry to the jam, thanks for making the game!

Thank you so much for your constructive feedback. I completely agree with you; the game is too punishing and the difficulty ramps up too quickly. I'll definitely fix these issues in a future release; your comments make me think I might turn this into a full game, not just a small demo for the jam.

🎮 Gameplay

The core mechanic is very original: you control two satellites that emit expanding waves, and pressing the down arrow triggers damage at the intersection point. It’s a clever and intuitive idea.

However, the execution quickly becomes extremely challenging. Hitting enemies near the bottom of the screen is especially difficult, and since no healing power-ups appeared during my playthroughs, the game feels highly punishing.

Some enemies release additional waves when they die, which could create advanced strategies, but synchronizing the enemy waves with your own is very demanding in practice.

🎨 Graphics

The visuals are very well made. The developer clearly drew the elements with care — everything is readable, cohesive and aesthetically pleasing.

The only small point of improvement would be refining the layout and typography on the initial screen, but that is a minor detail.

🔊 Audio

The audio work is excellent:

Sound effects feel soft, pleasant and highly compatible with the theme
Background music fits perfectly with the rhythm and atmosphere of the gameplay

The developer made very good choices for the overall sound direction.

💡 Innovation

Outstanding innovation. The use of wave interference and intersections as a combat mechanic is highly original and one of the most unique approaches to the jam’s theme.

🌊 Theme Interpretation

Perfect execution of the theme.

The entire gameplay revolves around creating, combining and leveraging waves. It’s both literal and mechanical — a flawless fit for the jam.

Thank you so much for your comment, it's really nice to receive one like this!
I agree with you when you say the game is punishing. 
I should implement bonus items and enemy variants to help you get out of sticky situations as you progress through the game. 
One trick is to use the waves of distant blue enemies (very fast waves) to hit nearby ones, but it's not so easy...
Thanks, thanks a lot.
