Strike Suit Zero is an interesting space Mecha game. Although the Mecha designation might not be the best here. First of all you are the only who can transform from a normal space ship fighter to a mecha which is much more powerful, however also more stationary. And there is only ship capable of transforming and you don't even have access to it all of the time. Most importantly perhaps is that your time in the Mech mode is limited, you can transform as soon as you gather a little bit of energy (which you can do automatically and very slowly over time, or quickly by destroying enemies), but you also quickly expend that energy simply by firing on your opponents. It seems that the only way they managed to balance the game is by limiting how long you can stay in the more fun Mech mode.
The targeting system also isn't very helpful, and there is no overview of what kind of enemies you're fighting. So the only way for you to get an overview of the situation is by actually looking around. That becomes very problematic in the later missions when you're tasked with protecting your fleet and you've got multiple enemy cruisers coming down on them, with your main objective being to destroy the beam cannons which do massive damage to your fleet. However as there is no overview there is no good way to be sure that you've actually neutralized the biggest threats. Unless you know for a fact how many of each ship is out there, which of course you'll only learn once you've failed the mission and that is simply not good game design.
Background music for the game is very nice, however it can become quite repetitive as there isn't much variety there.
The story itself is very generic, but still passable and kept my attention to the end (which comes quite quickly though), which is more than most other similar games can do.
All in all, the game isn't anything special but it's fun to play, at least through its short campaign.
