Thank you so much for playing! I like that idea, I think maybe a counter in the top left could have helped with that, there were 10 waves total so like _/10 would be a simple way to help haha. I was afraid of breaking the atmosphere but I think it probably would've done more good then bad if I had a counter. Thank you for the feedback! (If you saw ships shooting from the left and right of the screen you were close to the end, within 2 waves)
