The game looks super eye-catching but is really confusing. What I got from it is that you have to listen to the aliens make their sound, and then decide whether it's good or bad? I might be missing something, but a couple quick fixed before the jam would be:
1. I struggle to figure out which alien made which sound on certain occasions. Possibly just limit the amount of aliens that can spawn at similar times and/or play a quick animation when they do.
2. I can't differentiate between 'good' and 'bad' sounds. I may be missing something ovious though - but most of them seem ambiguous. Replacing with fewer more generic 'good' and 'bad' representing sounds would maybe be better, and also since the sounds are kind of annoying.
Just a couple tips before the submission period ends, and during my confusion I still managed to have some fun and love the art direction (:
