Fantastic tactics game. I confess I had a terrible approach at first. I lost my first attempt in the first level, and afterwards I was finishing all the levels with only 1-2 units left. I felt like starting again but I wanted to see how far I could get. I finished the first cycle with only Tewi and a breacher left, trusty Inaba-06, who, naturally, grew very fond of the commander. I lost my first medic. I had to play it really safe, baiting the enemy and rushing only when I had the upper hand. At one point the pathfinding was almost stuck, but she made it through. I made it to the last battle with only five units, so I had to be extra careful, but by then, my little squad had been through so much that their bonds had only grown stronger.
Overall, a really polished experience, and in 3D to boot. I especially commend you for the movement and shooting mechanics, and the YURI mechanic helped even out my losses, which made the game feel more fair.
Edit: Wording.
And while I'm on it, nice work with the levels too. wareya's tool looks pretty neat.
