Hello,
I'm excited to announce that The Sirena Expedition is coming to Nintendo Switch on the 16th of August 2024! The port has been handled by Ant Workshop (makers of Dungeon Golf and the upcoming Into the Restless Ruins), and I can confirm they've done a great job of it. You can pre-order the game in the following regions:

North America: https://www.nintendo.com/us/store/products/the-sirena-expedition-switch/
Europe: https://www.nintendo.com/en-gb/Games/Nintendo-Switch-download-software/The-Sirena-Expedition-2608616.html
Australia: https://ec.nintendo.com/AU/en/titles/70010000083376
If you haven't already bought the game, or you know someone who was interested but unable to play it on Steam, now's the perfect chance! And to coincide with the launch, the game will be 20% off on Steam for a week from the 16th of August.
See you at the bottom of the ocean!

Hello there! It's been a while, but I've got an update which includes some bug fixes, and also a bit of news. First, the patch notes:

Fixed a bug where you could pull a block backwards into a wall, and the block would slowly clip into you.
Made some changes to the movement code when going down slopes, so it's hopefully a bit smoother.
Fixed a bug where jumping as soon as exiting a ladder at the top or bottom could cause you not animate correctly.
A couple of tweaks to camera angles in two places, so that things are highlighted better.
So, with that out of the way, I'd also like to announce that; a) The game will be on sale at 50% off as part of the Steam Summer Sale, starting on the 27th of June, and b) The Sirena Expedition is coming to Nintendo Switch on the 16th of August! I'm very excited about the port, which has been handled by Ant Workshop (who also ported Thomas Was Alone and Lair of the Clockwork God).
Thanks again for your continued support!

The Sirena Expedition Soundtrack: Now available!
Well, it took a little longer than I was hoping, but The Sirena Expedition's soundtrack is now available on Steam! If you enjoyed the game, please consider picking up the soundtrack, as it really helps me out. Also, I'm really proud of it, so you'll be getting (in my opinion) 38

Okay, so I know I said the game was finished, but I received a report for a progression-stopping bug, so I spent a couple of days fixing that. Here are the details:

Fixed a number of issues with ultra-widescreen aspect ratios (wider than 16:9). There were two points in the game where you couldn't progress because the camera didn't frame your character correctly, and a number of others where it wasn't clear what you needed to do because things were offscreen.
Also fixed a potential soft-lock at standard aspect ratios in the second playthrough, where you could teleport to a block and then not be able to teleport back to it.
That's basically it! Nice and straightforward this time. Now, back to work on finalising the soundtrack.

Well, here it is! Finally, I've updated the game with all of the last pieces of music. There's about 15 minutes of new music, on top of the ~24 minutes that was there already, so I'm quite happy to have this in the game. Here's the full change log:

Added new music to the game, and updated all existing music to be mixed and mastered slightly better.
Moved a couple of pieces of music on the Rooftop around so that they triggered in slightly different places.
Fixed an issue where attempting to teleport from non-flat ground would often give you a message saving you needed more space around you, instead of telling you you can only teleport from flat ground.
I believe this is everything! I'm excited for everyone to hear the new music, and will hopefully be releasing a soundtrack soon. If you haven't bought the Sirena Expedition yet, I will be putting it on sale on the 26th of February, so you might want to wait until then to pick it up!
Thanks again to everyone who's bought and played the game so far! I'll post another update once the soundtrack is available, but otherwise, I think the game is (finally) done!
Kind regards,
Giraffe Cat.

Hello again! This, by my reckoning, will be the second last update to The Sirena Expedition. I'm currently working on the final bits of music, which I did want to get into this build, but I'm going to be showing the game at Debug U tomorrow and I wanted to get a couple of features in. These are:

I implemented new title screen cameras for when you have completed the game at least once.
I changed the way the save system works a little. Without wanting to get into the weeds too much, the way it previously worked was if you saved the game while dialogue was playing, it would put you back to where you were when the dialogue started; however, if you triggered multiple pieces of dialogue before the previous one finished, they would get queued up, and if you saved the game before the last piece of dialogue in the queue played, you would again go back to where you were when the first dialogue started. This could lead to you having to redo up to a minute of gameplay, which I never really liked. The way this system now works is that save states also get queued along with dialogue, so you always save where you were when the current piece of dialogue was triggered (which might not necessarily be the same as when it started playing). It seems like a small thing, but it required quite a big reworking of the logic behind this system.
Fixed a few minor bugs.
And that's it! I've got about half of the new music done already, and I'm excited to see how it sounds in-game. With any luck, the next (and final) update will go live some time next week. See you then!

Hello! It's been a while, but I've just pushed a new update. The major addition this time is a checkpoint system, and there are a few more bug fixes, as detailed below.

The new Checkpoint system creates checkpoints based on your game state at 6 points in the game. This is intended to be a fallback in the case that you lose progress due to a bug or forgetting to save, as well as allowing you to explore earlier parts of the game a bit easier once you've completed it.
The Checkpoint system will also create any checkpoints you havent passed through; this will only be relevant if you already have a save game prior to v1.08's release. If you do, you can load it up and continue playing, and once you reach the next relevant checkpoint, that will be created based on the current game state, whereas all prior checkpoints will be created with a generic game state. If you have already completed the game, and have a save game from that, loading it up and then exiting will be enough to create all six checkpoints.
Fixed the ridiculous issue where the bubbles on the Bathysphere at the start of the game would only play once, and if you started the game again you wouldn't get any bubbles.
Fixed the issue where certain bits of audio (mainly on horror events) weren't being affected by the sound effects volume, so they would be a lot louder than other sounds.
Made the sound effects for the eye that appears on the wall in one of the corridors much less abrasive.
A couple of other minor bug fixes.
Thanks again for your support! I've got maybe one or two updates before I'm calling the game done (outside of bug-fixes for any issues that might come up).
