Movement is slow, hard to catch the enemies.
Requiring a different laser for enemies is a great touch
Having a miss count makes it a little too difficult considering the short distance and slow response and movement speed.
Heat is a very cool addition, keeps you from spamming.
I believe I ran into an error. After all my lives had been spent was invisible then would spawn and continueing on I racked up another 1000 with lives that I shouldn't have had.
Love the game. These style games, the Raiden-ish fighter pilot games are one of my very favorites.
