Yo actually thanks a lot for the feedback! We know the game is tough and we like it that way, but feeling unfair is not our goal at all. We've actually spent the last week tweaking stuff here and there and we JUST pushed a small update that should make things a bit fairer while retaining the difficulty.
If you do give it another go tomorrow, be sure to re-download the game to get that new version. And just in case, a big tip I could give you is that only like two attacks actually require you to roll in order to dodge them, the rest you can dodge by simply moving in good angles. Good luck!
