I love the music. I love the innovation of the concept you used. What I don't like is the horrible AI of the robot you have to avoid. This game caused a lot of cheap unfair deaths simply because of the AI.
The big big big program is that the floating droid does not consistently follow the hologram. It will, for God knows why, suddenly turn around and float away. All at once it loses interest in your hologram, for no reason at all. It has caused me to spend way too long on levels, because I'm spending 10 or 15 minutes trying to bait the robot to go after my hologram when it refuses. It's like it almost seems too smart to know that hologram isn't me. So I'm either waiting for long periods of time for the droid to go somewhere else in the level, try to sneak around it and inevitably get caught, or I finally get the droid to follow my hologram yet all it once, it loses interest, spots me (even though its back is turned to me), and shoots me. Bam, I'm dead.
That's another thing- half the time the bullets phase through the blocks. This is very over powered and shouldn't be a thing. I want to say it's a glitch, because it doesn't seem to happen all the time but maybe I just wasn't paying enough attention to the trajectory of the bullets.
Again, I love the concept, but the AI desperately needs tweaked for the game to actually be fair and function well. I'm hoping you will make these tweaks so I can enjoy the game more.
