Really good take on the theme and object- this was rally a street fight, and glasses were prominently featured.
Graphics wise I liked the large hero silhouette the most- really sold the "I'm a baddass yakuza boss with hi-tech glasses". The rest of the graphics were all right, but the enemy design didn't really seemed "yakuza gang war" to me (I know, it's sci-fi neo-tokyo, but flying skulls were kind of strange).
Gameplay wise, there were two main problems.
1. Player had little incentive to move around the level, since all the enemies went to you.
2. Controls to change the glasses were a bit weird (why not just swap left with q and right with e). Because of that I sometimes just ran around, and if I wit something- only then swapped glasses to see it.
All in all- pretty good game, that needs some polish.
