Finally! I can't even remember how long I've been waiting for this :)
Reminds me of the fencing in Pirates on the C64 for some reason. Which is pretty cool!
I remember a game called Swashbuckler, or something like that, on the Apple2+. I just looked it up, not similar in any way, but I wish this game was what I had back then.
I played it this afternoon right after it came out for a couple of hours and had an absolute blast. It's super fun, and matches can swing back and forth multiple times resulting in lots of "damn it I was inches away from winning and now I'm going to lose no wait I'm back" type moments.
Tonight though... Ugh. Tonight I tried to play and the lag was so terrible that it wasn't fun at all. Think "I hit the jump button but it didn't jump and now I'm 5 steps behind were I was before" type rubberbanding/unresponsiveness. When it works it's incredible, but the netcode seems pretty terrible at this point. If you're going to be able to play it locally a ton you'll love it, but the jury's still out on the online part.
