Yup, the game is a rage-inducing one...LOL it was very creative though. I was surprised to see a lot of mechanics that changed up small bits of gameplay but worked together pretty well. I might need to playthrough more of the game to catch any other details I missed, but so far things are looking pretty good!
I do agree with Kano and ζοιδ. Some blind jumps were too brutal since you don't exactly know which direction to jump, which involves a lot of luck rather than purely the player messing up. The jump mechanic also should have some sort of "PowerBar" or Angry Birds-esc type of arc indicator, as that could help the player have a smoother experience. Also, no background ost definitely was another kicker. Having one could help ease the rage lol.
But overall interesting game! Also really well executed and I would want to come back to it!
