Good but needs work
Its an amazing idea just not nearly as indepth as it could be. If u make a sequal make a storyline. And the upgrades seemed to me like a waste of money so make a description of the upgrades and tell what they do to help. Overall though its a good game.
My favorite is 25 5 20 red bomb with insane damage.
i didnt have sound so i gave u a 0 srry.
