4 stars: I love this game, but wished there was a way to save progress so when I get a new phone I would have to start from scratch every time. Also the game zooms in too much which crops the game. These issues need to be fix please.
3 stars: the game is fun, but after level 100 everything is the same: the same enemies, bosses, level design, etc. Not only does it get boring, but the only way to make enough in-game cash to keep your upgrades on-par with the scale of the enemies, you either have to watch the ads after every level or spend real money.
2 stars: (Updated) A simple fun game the would be 4/5, but has several bugs, such as the HUD being the wrong scale and overlapping the play area, damage from previous rounds persisting into new ones, and special attacks frequently not working, which has caused me to lose many rounds unfairly. Update: the higher level you are, the laggier the game gets. Once I hit level 50, on stage 260, the game had become unplayably laggy and I had to uninstall.
