NintenDan, Bowser's punch is supposed to be powerful. I know that. But I think it's a little TOO powerful. 26 HP each hit if you mess up the action command? That's more than half of Mario's HP gone in one hit. Sounds a bit much. If Bowser uses the move three times in a row, whether you use Mushrooms or not Mario is FINISHED. I found it difficult to time the hammer defense since Bowser pauses for quite a while and during this you cannot hit him, and than suddenly lunges forward. You have to be quite precise with the action command to get it right, and you need to time it a bit early.
Also, the HP doesn't quite scroll all the way off the screen, the bottom of it sits at the very top. You may wanna fix that by either making it permanently visible or removing it from the screen completely.
Other than that, I think it's pretty good! Some sound effects and music would probably finish it off.
Thanks for the feedback! I wanted to get most of it done this weekend, with just a few things to tidy up, and this is the kind of stuff I was expecting. Better it get pointed out than not get pointed out at all. Oh, and yeah, I made his punch that powerful just so I could quickly test if I could die and forgot to reduce it, whoops.
With the punching and the flames, I can make the delays quicker. Right now I've got it so that the delays are actually random (from 0.2 to 1.2 seconds, I think. Well that's what it's supposed to be). That was just to make dodging harder, by I should be able to reduce it down so there's a 1 second maximum wait.
