Having a better understanding of the Invaders boom in Japan, and after actually giving it a fair shake rather than just disregard it as "slow Galaga", I've come to appreciate this game more than the first time I encountered it. It's basically Space Invaders with a little more excitement, and it's fun. It has the same fun of finding the best shot timing and positioning possible, just with some layers liking dodging incoming enemies and the "escort" bonus when it comes to the enemies at the top of the swarm. Just a nice time, that's all.
