I think it takes too long to be able to get to see the store even though it felt I was collecting many coins for upgrades which meant that soon the aliens became way faster than me and more in quantity than my super slow shooter could handle. Auto-fire is fine but I also felt less in control and would've like the option to let me control when it fires since often times the shot was wasted while I was turning towards the enemy and now had to wait for the cooldown to finish before it shot again making it harder to play than it already is.
