Deflect issues

This game works perfectly on the iPad mini, but, I cant get past the challenge that features Kano. The problem is that one character model of a thug can always get past my deflect attack. It gets annoying and it Drains my health making it an issue for the next 3 people I have to face. Sometime dodging doesnt happen when you tap or does a deflect when you dont mean to. Please fix these control issues. Plus, paying for a skin in a game that was 6 bucks is totally in-excusable.
