Left to rot.

Awake once again.

Welcome back.

One last task.

Enter Siphonopolis. Find the heart.

> What am I looking at?

This game was originally made some time around 2017-18. It was hard to control and used poor 3d renders for its graphics. The plot was barely there. So it was forgotten and deleted.

But it didn’t die.

Recovered from beyond the grave and the recycle bin, it has been fixed up, polished and remastered with a new photo-edit artstyle using stock images, old project renders and even a few pixel art drawings. Every asset has changed, becoming more twisted and strange. The story has changed in a similar direction.

> What am I supposed to do?

Siphonopolis can be called a point-and-click game, but it’s a rather odd one. There are a few puzzles but they aren’t the focus. Most of your time here will be spent swimming through surreal landscapes, fighting bizarre creatures in bullet hell combat and running away from the ones you can’t shoot.

> How big is this trench?

The original game has 52 short levels. A few more with new mechanics have been added to this version, which now has 70 levels. It's a short trip, but it doesn't end when you find the Heart. Completing the game will unlock another salvaged bullet hell game and 3 alternate protagonists for the main game with different gimmicks each.

i tried to play the game with Parallel desktop (on mac), but it couldn't run (or flash quit upon starting)

but MAMEP works tho


Honestly I don't really know if this can be solved. This thing runs on and old engine and I haven't been able to get the export options for anything besides Windows working :(

Only thing I can think of would be getting a Windows VM and copy-pasting the executable there.

thanks for the reply:) will try a different virtual desktop tho, but the game looks really great!


game good bug bad😁👍

Can you give more info about the bug? Knowing this project, it's probably some dumb mistake in the code.

Is this game using a custom engine?


No, it uses an old Game Maker version (1.4.1567) because that's the one it was originally made on. I tried porting it to Game Maker 2 once but it didn't work.


Ah, I see thanks! Also great game, im digging the surreal artstyle :)

What earthly substance do I need to consume to fully immerse myself in this art style?


virus detected?😦


Sorry to be the bearer of bad news, but whatever antivirus you're using isn't good and is giving you false positives.

It's probably a false positive, antiviruses tend to hate single .exe files. I always get a warning from my own antivirus when testing a new version of this game and no virus (yet).
