Sorry about that. It's just that I did not want to include any 3rd party assets for this one. And for audio I just used a code (first time generating audio via code). I will add some music and sound effects after the jam. The idea about adding a sound during wave change was helpful. Thanks for letting me know.
I often end up making my games too hard to play, that was the main reason I made it a bit easy. Thanks for the feedback. I will make an update maybe in the future and will definitely consider adding a different mechanic to player movement (A fuel bar or something). Also thinking of adding it to play store along with maybe something like spaceship upgrades and proper levels.
