I just don't know what to start with.

You had to put a lot of work in this game. It looks great! I played it but it just isn't my type of game. 

Controls were really hard to me. Maybe because it doesn't have perfect tutorial. It just throws player in doing everything from the beginning. I spent a few minutes thinking how to travel to first objective and almost closed the game. Travelling between star systems and planets was really confusing.

Fighting system is too dull (but again, maybe it's because it isn't my type of game). Watching my big fleet shooting straight ahead instead of aiming at one last enemy wasn't the greatest time of the game.

Also, genre is a niche but watching you updating this game and doing so much work... Wow. I'm impressed! Keep it going ;)

Thanks a lot for the feedback!

It is great to get specific details on what needs to be improved.

Now I know what to focus on in future updates. I appreciate you taking the time to try it out!

I like this game :) killed a lot of time on it :) I am getting an CTD error in Aanon that is repeatable and also randomly hits everywhere else as well.

  " Uncaught exception thrown in Thread [LWJGL Renderer Thread,5,main] ArrayIndexOutOfBoundsException: -1 " 

Im guessing its a bug , I have gone over my PC and I pretty sure it meets all requirments, if it would help I can provide whatever info is needed ..   it hits every time in aanon after I warp in within 30 seconds, I have tried everything I could think of to find what in aanon is triggering it , with no luck.

I was able to do do Aanon and a few other quests after that in ver 1.0  .   this error started for me with ver 1.1 and no change in 1.2 .

Yes that sort of error is definitely a bug and not a problem with your PC.

That info should be enough for me to replicate the situation, I should be able to fix it in the next update.

Thanks for playing and for the feedback! 

You helped me squish one more bug :)
