Thanks for playing, I am glad you thought it was a fun game!
Yes, the space to dash should not have been in the final release and was completely unintended. I had coded it but I scraped it, yet I never removed it because I had forgotten and so animations obviously don’t exist for it.
As for the game being generic, I can agree that it is just a bullet hell at its core, and the only unique part of the game is the mirroring enemy ship which makes it obvious their bullets are aimed and the fact that all of the bullets are spawned to the rhythm.
It could have been more unique, but limited by time constraints, I could not implement an idea where the player would shoot during the bullet hell by pressing any keys on their keyboard to represent buttons on the control panel of the ship. If this was implemented, I could have a good way to put score in front of the game and make it a lot more interesting!
