About this game
The basics
How long can you survive if you are the only one fighting against the whole galaxy?
- Arcade-style twin-stick shooter action;
- Each phase brings a new type of enemy to make your life more miserable;
- Collect bombs to clear a path for ultimate vengeance;
- Survive as long as you can and, who knows?, maybe you can be the last one standing!
What you get
Fast-paced gameplay for those times when you only have a couple of minutes to play something and just want to shoot stuff up (and try not to get shot at!).One Against The Galaxy was designed and developed by a single person, a game designer who decided to prove you can make a fun game with a low budget and if you focus in the right direction. Hi, that's me!
Feedback is not only appreciated, but encouraged. This is not a "complete and done game". For the next few months I will update it with new balance, new enemies and new... well, almost anything you - the player - wishes to see in the game, as long as it is feasable considering the budget I have for this game. Which means: the more it sells, the more I can invest in improving it!
Have you found it too easy? Wants to see something different? Saw something you didn't like? Let me know, and I'll do my best to work on it!
Thank you for your time. I hope you have fun!

Dozens more Achievements for you!
Hello, pilots! The second update of One Against The Galaxy is up with: * 48 new Achievements! Use bombs, kill the enemy, and die a lot! * Fixes to the interface effects as requested! * Full-screen also as requested! * A little extra balancing on the first couple of phases! And how far are other players going, you ask? So far only EIGHT players managed to reach Phase 5, and no one has lasted until Phase 6. Who will be the one to break this record? You, maybe? Then get to shooting! The Galaxy is waiting for you! - JMBeraldoRead full article on Community Announcements (Eridanus Studio)Patch NotesOfficial

First update ftw!
Hello, pilots! A quick update just went up. Other than a few minor bug fixes, it brings in Simplified Chinese localization for the whole game. Seems like the game is quickly becoming popular in China, with almost as many players as in the US, so, why not help our friends out there understand the game a little better? I hope you enjoy it! On the next update I'll check the volume of sound effects and music, tweak game balance for the mid phases and investigate a couple of bugs that came up. Let me know if there is anything else you guys want to see in the game, and I'll accomodate it in my To Do list. Thanks! - JMBeraldoRead full article on Community Announcements (Eridanus Studio)Patch NotesOfficial
