This is fun fighting game; however, I can't see everything on the screen and flash didn't give me the option to zoom out.
You might want to work on fixing the game's screen size to display every last detail.
The controls seemed to work just fine.
The fighting game engine seems to lack a life bar for each character.
I have no way of knowing how much damage is happening to either me or my opponent.
The characters don't bleed, bruise, break bones or get any kind of contusions during battle.
The lack of onscreen injuries is the sort of detail is easy to overlook in a fighting game.
Since damage can be depicted using other methods.
A life bar that displays damage is a common feature of fighting games that is often taken for granted.
Your audience expects to see life bars in their fighting games.
Other ways of displaying damage during battle is by making the sprite flicker with a strobe light effect.
I remember the bosses in TMNT video games would flicker as a way of displaying damage.
displaying damage in someway in fighting games adds an extra element of suspense.
You can become extremely excited that you have almost defeated your opponent.
Showing signs of visual damage helps to build a certain level of fear or anticipation in fighting games.
A life bar, injuries, blood, flickering are all possible ways to display damage in fighting games.
I assume you were aiming for a younger audience with this fighting game.
It is still not excuse to avoid including a life bar as a possible feature.
The lack of life bar is merely a small nit pick and is entirely optional.
Bushido blade did not include a life bar and fights were typically over quickly.
The sprites in your game were directly taken from already existing video games.
I honestly would prefer to see the anime characters drawn in your own style.
You could even create your own gaming sprites. backgrounds and animation effects.
This was a fun game overall but screen size is entirely too small to display all the necessary details.
Just fix the screen size and consider the rest of the review to be nit picking with optional ideas.
I like your game so far.
