Since you've mentioned that you want to make a larger game based on this, I thought I should come back and give a more serious review.
As said in the original review, the controls in this game are some of the tightest I've experienced from a free online game. Moving, slashing, jumping out of the slash combo, spraying fireballs to stay airborne, dashing, wall-jumping. All you'd need is being able to reset the double jump with a melee attack and you'd have a discount Devil May Cry! The little screen shake when hitting enemies goes a long way towards how good the game feels, too.
With that said, the game is very basic in it's current state. It takes a very long time to do one run of this game, upwards 10 or 15 minutes, which is a long time to be fighting, even in the best of circumstances. Having only four basic enemy types and one arena makes that long fight quite repetitive over repeat runs. And since you have to get currency to buy upgrades to make it further, that repetition does set in after a while.
I want that bigger game to be as good as possible, since you've got a great base for it. That's why I was harsher with my review this time. Great work! Can't wait to see what comes next.
