Yeh, those guys are harder due to different attack patern. Basically you weave damage in between their attacks - moving out and in again for it. We posted video of walkthrough now to help people just in case mechanics provided too much difficulty to understand. We forgot that encounters are only easy from get-go for us, since we know how they work...
Menus were rushed, so no saves/restarts, unless you die, unfortunately :<
Thank you for trying out our game by the way! Means a lot!
