Bugs noted:
Still with the missing font. I did some digging, BankGothic is a copyrighted font so technically you can't distribute it and we can't get it for free :/ I would suggest using a more standard font.
After combat the bullet icons stayed on the screen.
After combat the combo icons stayed on the screen as well.
Shane's swagger kick pops up a couple error messages, but doesn't halt gameplay. The first shows a number, the second says true.
Gameplay notes:
I would suggest highlighting the character or his frame when he's active, the little bar being full isn't terribly obvious.
Your low HP yellow color is really hard to read against the background.
I'm not sure if HP were resetting on death or what but my HP kept refilling?
With the above in mind, I didn't have any problems with difficulty.
Opinions:
The animations, battlers, and title screen are awesome! The music is snazzy, not to my taste but good quality. I'm definitely digging the battle system, but I sincerely hope you plan on introducing it slowly and carefully. It was a lot to just jump into : ) I'm going to keep messing with it, when I get back online in a couple weeks I will try to post more thoughts.
