Hi Pro Igrok,
I checked out your recent video updates (the March 10th video and the March 27th video).
Your progress is impressive and great so far with the attack moves (some examples: Leonardo's spin-propeller style attack, katana style uppercut, lifting enemies over with the katanas, and double katana downward floor attacks) and combo hits! Awesome stuff!
The only problems, and they are small though, is just the sprite images. Sometimes I noticed Leonardo having the wrong weapons during the attack or when he falls down ("Shell Shock") by having Raphael's sais. Keep doing that cool stuff you do!
