Nice game, the visuals are very funny and music is in accordance. The main problem that I had is that when shooting, is very difficult to control the amounth of pop-ups that you fire. It would be nice if instead of shooting while you keep mouse button pressed, you only shoot one pop-up every time you press the mouse click. But if you want to keep that, maybe another good idea is refilling all the player ammo when you kill an enemy instead of refilling only pop-ups that hit the enemy.
