Wow great work, love the arcade music, love the powerful rush of obliterating a whole wave of enemies, even if most of them are phantoms. I was really enjoying that. Just a small note - there started to be huge lag around wave 11 or 12, just for the initial few seconds of spawning. I suspect this could be solved by using object pooling for your enemies? (Let me know if you'd like me to cover it in a devlog but there are plenty of tutorials out there that cover it). But overall, very fun game!
