Oh, I’m doing that 🙂 Spending all the money on weapons. But when I reach episode 2, my weapons can’t manage to destroy any of the enemies before they fly off screen.
There are also some free upgrades you can get during certain levels. I think collecting all of them, too, would help.
But yeah, I don’t kill enough enemies to get enough money to buy enough weapons for episode 2, which in turn means I make even less money…
