Very glitchy. On the plane level it took four bullets to the head before one actually connected with the guard. The final gun doesn't work at ALL. It's a good game, but the glitches bring it down.
The hard badge was rather annoying. Got to 169 a few times and the boss destroyed me. But perseverence is the key. One thing I'd change though;
Kicking. It's too over-powered, and being able to chain kicks makes the game too easy when facing single opponents. This goes for the AI as well though. I lost 3/4s of my health from one swordsman through him kick spamming.
