About Siphonopolis

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This game was originally made some time around 2017-18.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.

What Steam players say

✦ AI summary

Players are drawn to this game's weird and distinctive aesthetic, interesting lore hidden throughout, and generally cool atmosphere, though they note it suffers from significant technical and accessibility issues including motion sickness, bugs, and a missing colorblind mode. The gameplay can feel repetitive over long sessions, and while some find it entertaining and moving, others find it difficult to look at and play. Most agree the game has potential but acknowledge it needs polish and quality-of-life improvements.

Weird as ♥♥♥♥, but damn did it keep me entertained. Weirdly, has some pretty interesting lore if you can piece it together with the bits and pieces it gives you throughout the game. Damn would I love to see a review or deep-dive about this game and the lore. Wouldn't recommend playing through this in one sitting though since it's pretty long and can get pretty repetitive at points but I can recommend you try this game out!

I haven't finished it yet, but the graphics are cool, and the story, what I saw of it, felt moving.

Haven't played too much of it but it's super cool from what I did play fair warning though, this game is very motion-sickness inducing

Really cool game, but for some reason, unfortunately it's lacking a colorblind mode that I could find. I can barely tell the difference between the red projectiles and the backgrounds, which is very frustrating. I wish I could play more. Also, on the first food-gathering level, I ran into a bug where the food-processor couldn't be talked to, so I couldn't finish the level.

The game has so much potential
