Have it, love it. It seems easier only because they give you a LOT of like back now. Save points do it once, and after every wave of enemies they give you some life too. This is offset I think by getting jumped continuously and kamikaze dudes who blow themselves up. The bosses are still as hard as ever though (i agree that the second stage boss is /wrist worthy...). I'm having a lot of fun playing it, and should do great to fill the gap between now and MGS 4 haha.
