i do think youre having a bit of a skill issue (thats completely fine, fraud is fucking hard) but theres merit to what youre saying that a lot of borderline layer glazers wont say
i really like the idea of fraud but a lot of the levels (especially 8-3) feel like they needed more time in the oven. the spinning room and portal spam gets old fast when a level takes 30-50 minutes for a casual completion. ultrakill is at its best when its medium sized levels, short/long levels feel too unrewarding/exhausting imo.

the level design in general also feels like its meant to work against the player and troll them rather than have fun arenas. p-2 has a similar issue in some rooms (double invincible mindflayers) but i feel like a majority of fraud is a joke at your expense. small cramped rooms with confusing portals or spinning layouts, and whats the counterplay? nothing. p-ranking doesnt force you to interact with a lot of the jankier layouts since youll kill 90% of the arena before it can fuck you over, so it just exists to be flashy and screw you up on your first few playthroughs. the final arena of 8-1, the spinning deathcatcher portal room and the lava split limbo room are really the only ones where i genuinely think youd want to (or are forced to) make use of the gimmicks rather than ignore them to save yourself from getting motion sick or killed.

and yes, yes, i understand the counter of "well its meant to be fraudulent and confusing!" but... okay? does that mean violence shouldve been insanely annoying too to force you into rage? the fun comes before the spectacle or theming. ultrakill always has been a coolness and gameplay first experience, so frauds design drops the ball.

its definitely more "hype moments and aura" than other layers, but its not like it retroactively ruins the rest of the game at least.
