Quality of Life
Streamlined Ship Stats: Spaceship base stats are now displayed as a sleek strip directly beneath your ship. No more clicking through tedious info buttons just to check your base stats!
Fire Rate Visibility: Your current fire rate is now displayed in the gameplay stats panel for easier build management.
Balance Changes
Neptune (The Hunt): Damage type changed from flat to percentage-based (%). Just like the recent dash adjustments, this ensures the skill scales properly and remains a powerhouse in the late game.
Fauna: Base Critical Hit Chance buffed from 20% to 25%.
Victoria (Overclock): Resistance reduction decreased from 50% to 30%. I want to see some highscores with Victoria!! :)
Bug Fixes
Fixed an exploit that allowed players to infinitely "farm revivals" using the Reboot Core artifact.
A Quick Personal Note: Introducing Grazed!
Just a gentle reminder that I am currently working on a brand-new title called Grazed! It is a fun, bite-sized arcade game built around short sessions and satisfying incremental updates.
If you enjoy my work, I would be incredibly grateful if you could check it out or drop a wishlist; it helps a solo dev immensely!

Announcing GRAZED: A High-Risk, High-Reward Incremental Arcade
I am thrilled to announce my next project: GRAZED! Grazed is an arcade incremental game built around one golden rule: to kill, you have to get in range of dying. Push your kill combo high enough to ignite absurd powers and chase the highest score. Death isn't the end; every run e

What's New
New spaceship Victoria:
A high DPS and bullet-spam spaceship.
New Skills: Focal Power and Overclock.
New Trait: Iron Will
New spaceship Fauna:
A high defense spaceship based on survival.
New Skills: Giant Growth and Nimble Dart.
New Trait: Adamant Carapace
Russian is now fully available in-game.
New artifact Kinetic Core increases collision damage based on Max HP (pairs nicely with Fauna).
New missions: Cosmic Wrath, Space Typhoon, and Juggernaut.
Added a "total damage" stat in the pause menu stats panel.
QoL improvements
Balance update: the collision damage cooldown from the spaceship has been reduced from every 1s to every 0.25s to enable the possibility of collision-damage builds.
All dashes now deal percentage damage instead of flat damage (relying on them in late-game for damage is now a thing; this also helps the new collision damage builds).
Bosses in endless mode are finally randomized (which makes it more fun and easier to complete some missions).
Moon and explosive alien explosions are now more visible.
Fixes
Fixed an issue where negative resistance wasn't considered (e.g. using the artifact Glass Cannon was free damage). Various fixes and improvements.
Support the Game
If you’re enjoying the game and haven’t already, please consider leaving a Steam review. It helps a lot and directly supports future updates. And if you’re having fun, sharing the game with friends, social media, or to your favorite roguelite streamer, makes a huge difference!
Thank you for playing and for all the support so far!

Arcadium - Space Odyssey is finally out on Steam.
What started as a small experiment slowly became something much bigger than I ever expected.
This project went through many phases: excitement, doubt, rewrites, and moments where I genuinely wondered if I’d ever ship it. Seeing it released today makes all of that worth it.
The release version represents my best effort to deliver a game that feels complete, polished, and fun to come back to, built with a lot of care and constant iteration.
The release includes:
15 depths, including an Endless Mode
12 spaceships, each with unique skills and a passive ability
40 artifacts, 51 talents, 72 items, and 7 relics
150+ planets, including contaminated and gas planets
Everything that’s in the game has been tuned and polished to feel solid, responsive, and ready for long-term play.
But this is not the end of the journey.
What’s next:
Japanese and Brazilian Portuguese localizations are currently in progress (thanks to the fan translators on Discord)
Endless Mode leaderboards are planned
New spaceships, artifacts, items, and relics are planned
I’m also launching on mobile in the next weeks, and I am going to explore other platforms as well, including Nintendo Switch
Community feedback has been incredibly important during development, and it will continue to shape the future of the game.
If you’d like to be part of the community, share feedback, or follow development more closely, you’re welcome to join the Discord:

I am excited to announce that Arcadium – Space Odyssey officially launches January 26.

Feature revamp - Stars:
Finally now stars are a full blown feature!
You can now find Star Crucibles in the middle of Stars! Burn all your good to get powerful items...even star-exclusive, legendary items!! (e.g. Living Sun item).
New star aliens, they now can drop gold.
Stars are now bigger, spaceship heating up is slower.

From the planets "lightest spot", you can now better tell where is the closest star.
New spaceship: Aestas (unlockable through stars interactions).
New minibosses: Alien Splitter, Alien Spaceship.
New stage featuring planet sentinels.
New missions: The Golden Offering, Tyrant Reaper.
New artifact: Hyperfocus Lens.
New items: Galactic Cookie, Lunar Cheese, Living Sun, BioHull Impactor, Starpiercer, Fusion Core.
Game Improvements
The stages are now 12 minutes, rather than 15 minutes.
Merchant no longers run out of items (always fresh items available!)
Balance improvements (talents, ships, items, etc...)
The tutorial has been improved with better pacing and videos, including information about perfect landings (the most asked question in the game).
Base movement speed of all ships has been increased.
Bug Fixes and General Improvements
Fixed an issue where percentage healings of HP and energy were scaling with healing or energy bonuses.
Fixed an issue where the selected artifact details were not updated when browsing artifacts with gamepad.
Fixed an issue where celestial beacons showed both the blue arrow (item) and the orange one (fight event).
Fixed an issue where wishing space rifts rolled different items if you resumed a session.
Fixed an issue where only one visuals for moons was present.
Fixed an issue where, upon resuming a session, the same moons and planet defender aliens could re-spawn.
Fixed an issue where mission tiers didn't take it well when the game was updated and their requirements were changed.
Fixed an issue where the background could flash when defeating enemies.
Fixed an issue where passive items and artifacts were not selectable with gamepad.
Fixed an issue where reaching -1 defense would fully unlock Quest for Aegis.
Fixed an issue where contaminated planets started appearing from stage 6 instead of stage 7.
Fixed a few issues around gravity attractions with moons.
Fixed an issue where cloud load would not work.
Various fixes and improvements.
Of course, these changes are those applying to the release version, but many of them will touch the demo version too.
I am also working hard so that the full Steam release (along with mobile) will be this year (2025), and no further :)
