Hey I got it working on a different browser, fun stuff! Sick Jump Man! Wooo. I agree about the air attack thing, sometimes coming down to land and the bat is right there, I could have got him with an overhead air attack!
I found the automatically zooming out camera to be annoying (especially when I hit a wall and it ker-chunk zooms in a lot instantly), though from a game design perspective I agree with Tiger's assessment, it is good to have and most players will like it. I believe I'm in the minority on this one, but for my own games going forward I intend to make the camera zoom automatic by default, but have a manual camera mode option for people like myself. (I just want to see what is ahead regardless of my speed!)
This one is fun, I look forward to any updates you make to it.
