@Sabiarts Thank you! Yeah, really wanted to try move the focus of the actual player doing the majority of the damage to something which they're able to spawn to help. If I were to keep working on it, I'd probably add more types of objects you can summon.
@Rhornbeck Thanks! :D Yea wave 10 is pretty hard, I can only get up to wave 11 myself! The counter was an important addition I think, and I'm glad you mentioned it! I felt it was necessary as you couldn't have a full view of the entire room. I feel it's pretty unnoticeable when it changes/updates however, and if I were to keep working on it, I'd add a small animation or colour change on updates - same goes for the entire bar actually!
