Solus Games has released a free demo version of their fighting game called Funky Punch Lite [Free, App Store].
Fortunately, the full version has since seen an upgrade which adds difficulty levels as well as skill belt accomplishments to earn. Difficulty can now range from Normal, Hard, Crazy Hard and Ultra Hard.
The demo provides both training as well as the ability to play two of the 12 characters. Overall, it gives a very good taste of the full game.
