I really love this game! I'm not sure what the other dude said about there having no cayote time but I am pretty sure you did add cayote time. I also noticed the jump buffer (pressing jump before landing). These are the little things that I test in all platform games I play. So far, your game was the only one with both. Nice one!
The game reminded me of megaman the most. The levels were a bit rough but nothing so bad that would ruined it. I actually didn't mind at all but having said that, there is a lot you can do to make this game even better. I was able to defeat all three baddies and get 3 specials + 2 sword moves. I believe that is all, right? I found the difficulty of the game to be just right for my taste. :)
Also, the bg tracks were awesome and the sfx is reminiscent of the old days. Though I think maybe lowering the sfx volume to maybe 25-50% would make things better.
I would really love to see a newer version of this!
