The moment I read the readme, I though this map was going to be another Duck Hunt look-alike, since it bears the title "Space Invaders". Although I did see those bugs from the Atari game "Galaga", this map is something else.
Gameplay is different from the norm since you start with a Plasma Gun, and that you typically spawn on top of a jump pad sending you onto one of the blue ring platforms orbiting planet Earth, which has a Rocket Launcher and Quad on top, as well as a pair of cherries below.
I thought the item placement was okay. I personally was not too fond of the lean health throughout the map, but then that is just me.
While the caterpillar and ghosts remain static and distant, the Galaga bugs nearby are jump pads for you to get to the Red Armor on the green platform above the globe, as well as that quad.
I like how falling into the void just teleports you to the rings instead of killing you. For this kind of style of map there is no other choice really.
Pretty good map.
