Cool concept! I wish there was more sprite variety. The shooting mechanics worked well, and I enjoyed them. Music could do with more love as it gets repetitive fairly quickly. The overall vibe worked well but there are places where graphics weren't pixelated that feel a little odd due to not being as consistency pixeled [menu buttons during gameplay for example]. Thank you for participating!
Thanks for the feedback! I'm not the best at composing music, and while it is one of my better tracks I too found the melody drilling into my head after a while ¯\_(ツ)_/¯ The UI was kind of rushed, and I would have pixelated it with more time (Unity's pixel perfect camera irritatingly can't pixelate UI, so I'd have to do it manually :-( )
