Oooh this has so much potential! I LOVE the idea, but currently the gameplay has too slow of a pace. Maybe let the player fire more often, while also spawning more enemies, and less errors that lock the whole thing up.
thank you for your feedback, I had a lot of trouble balancing the difficulty (I make usally to hard games). But I'll keep in mind to raise the difficulty on the middle and end part of the game in the postjam version :)
