Played the game a bit more. A "Produced By Omega Force" screen does come up in the beginning...but I'm guessing that it's just that- produced by them, because in game it lacks polish.
I think the game is a bit better than I initially though, but it's still pretty average and I don't like how some characters, at least initially, don't have two weapons to use. The menus seem to indicate that they can get more weapons, but I'm unsure.
I started just skipping the story sequences entirely because they're A) entirely too numerous and B) just semi-animated versions of the story I already watched in the anime series. The levels follow the story pretty closely, which I like, but a lot of levels I played feel like you can just run past everyone and get to a goal and/or take out one guy to end everything. There's nothing really strategic going on here so far.
Also had a nasty glitch, when playing on Gieve's first stage, where the camera stopped and stayed in a fixed, static position. I was still able to move around freely and managed to beat the level by using the mini map, lol.
