It's a pretty good roguelike, but I do have some complaints.
The plasma shot can move way too fast for a human being at the higher upgraded speed levels, the AI can use a speedy plasma shot to hit your planet in the blink of an eye.
I don't like the need to level up to get more starting money. while in theory a player could beat the campaign the first time, it's extremely unlikely vs playing again and again to get a larger starting bonus.
Missiles need to glow either red or blue to let players know if it's their missile or not., I wasted two shields before realizing the missile was reflected and flying on a wide arc away from my planet and towards the enemy. For a weapon so deadly it's easy to not actually see it since it lacks bright colors like every other projectile in the game has.
I like the idea of the railgun, but it's frustrating to fight the AI using one, it hits instantly and the AI has near instant reflexes vs the player. I found my guns getting shot before the enemy railgun was even fully on screen to act against it.
I need a target reticule to help me aim, it's extremely difficult to line up emp and reflector shots while the AI will have no problem hitting a moving target.
Overall, I love what this game sets out to do, and it's definitely one of the better roguelikes I've seen.
