Thanks a lot! And unfortunately I think you experienced a bug, there was one(maybe more) enemies that I forgot to make delete themselves when they got off screen, the one I know of is the plant one, the rest should handle themselves. And yeah, I was using an 8-bit colour palette and could only find that colour that worked well with the health bar, looking back at it now though I definitely could have just tried a slightly red black or something. Anyway, thanks for playing!
