Cool game to play.Remidns me of both happy joyride and flappy bird and was fun to play.İf you thing about developing it further you could consider a mobile version.
Alos there was a 2 stuff thatbothered me.The first is tutorial sadi one had 10 lives the game i had 20.And with 20 it was waay to easy but still when i came to 1500 score i still had 14 or so lives left.After a while it bored me out.And to make it harder i think the balls should spawn more often on the edges cuase there would be like 6 astroids that would go through the middle so i could just stand without doing much.
Itsa very good game thou cant wait for the updates to see hoe the game develops.
