Hi. You should first of all fix bugs and collision with enemies. The arcade game was difficult, but a little more tolerant when enemies were hitting the hero: he could hit them with his knife and have his life saved. Many times in your port I had the feeling I was killed with no reason by a enemy.
Moreover, I also noticed sometimes grenades launched by the guy at half of level 1 just hit the hero with no conseguences (no collision detected), and it happened that I was killed by a soldier at the end of level 1 just to gain access (with animation too) to level 2 when I restarted.
Here at italian Zzap! we decided to wait for your action, before reviewing the game, because we felt it's better, even though we'd really have liked to publish its review on incoming issue #4.
