The game is supposed to be a bit frustrating, it's inspired by Jump King and getting over it and those games are way more frustrating, that's, in my opinion, a fun-to-play genre but of course, it's not for everyone,
for the randomness part of your review, no there is no time where you are not 100% sure of the platform, you probably haven't read the description of the game or wasn't focusing while playing.
anyway, have a nice day and thanks for playing<3
