Planet Intruders

Goal

You have to protect (unexisting yet) planet in the middle from the (unexisting either) ships, that shoot at it by placing tetris-like blocks or shooting with tetris like blocks at them

Controls

Arrows (left and right) to move

Z to place/shoot

X to rotate

A to change mode from placing to shooting and vice versa

Shooting mechanics

If any placed block obstructs a shooting piece, then it will destroy all the placed blocks nearby. To fully grasp the concept, imagine that a piece is an actual bullet coming from the center of the screen to the edge. Are there any pieces that will hinder its' movement? Then it won't shoot and  will destroy obstructing pieces.

TODOs:

- upgrade collectors to bring more resources

- buy collector small, buy big

- add one building layer

- add shield that reflects one shot
