My summer vacation ended today, but I managed to get some work done on Gridblaster the last few days. Here’s the latest screenshot. You’ll notice the extra blocks in the maze.

Here’s what those blocks do. If you hit them on the right side, they fly all the way through the maze and then back a bit. For example, when the block closest to the vertical edge of the maze is hit from the left, it will first move all the way to the right side of the maze, back to the left, and stop two blocks right from where it’s now. When a block hits an enemy, he’s destroyed. The block will also keep moving, so it’s possible to score multikills with them! The player himself can’t get hit by the blocks.
There are four blocks in the maze. Two can move only horizontally and the other two can only move vertically; this is indicated by the arrows on the blocks. They will also only move when hit from the outside. For example, the top block will start moving when hit from the left but not when hit from the right. After it has been hit and takes the new position on the right, you’ll have to hit it from the right.
