Rogue Star: Shoot em up with customizable skills and epic boss fights

Hi I'm looking for feedback on my early access game Rogue Star. Its a shoot em up with 10 different customizable abilities and rogue like bonuses that increase your power or increase the difficulty but also rewards. You fight waves of enemies and then finally a boss at the end of a galaxy. Defeating the boss unlocks the next difficulty and new rewards to earn. It has daily quests and long running achievements to offer more rewards and leaderboards to see how you stack up against other people. I'll be adding more game modes in the future but I wanted to test that the core gameplay was fun and easy to pick up.

Let me know what you think, I appreciate all feedback!
