Nice concept. Some SFX would had been welcomed. The drone module aggregation, add some force feeling. You share some common core feature with our game (the first I saw for what I plaied). Good execution, control and music. Well done.
Thanks anyway for playing! :)
But you are the second person that says that SFX are missing yet everything should have a sound effect.
Did they not play for you? Maybe theres a bug i don't know about ^^
