The laser is WAY overpowered. It was the first thing I bought after level 1. Never again did any enemy survive, and most of them never got the chance to shoot at all.

Bullets should be a different color so that they are easier to see on the screen when going over landscape that is the same color. It was hard the first couple of times till you learn to place upgrades.
