Thanks for playing my game and giving feedback. It's my first game so all feedback is greatly appreciated.
The spawn order was next off my list to do before I ran out of time. The fact you noticed means you must have done a few run throughs - that's a positive for me.
I had a list of other things I could do if I time or come back to this one: better sounds and animations, more stages, more enemy/ally images, more 'tricks' to confuse player. I'm just pleased how much I got done in 2 days.
