of course it is not. i stumbled upon this and saw the 1 star rating and thought, can it be so bad? probably not. but there is stuff around a game that can piss off users. like a botched setup routine. a setup exe is almost always slightly bigger than a naked zip. after all, it has the self extractor and probably the setup routine unlike the zip wich only has the payload. this zip is 1/3 bigger than the exe. i have played lots of rather big games and none ever had a setup routine on itch. not even the commercially successfull ones like baba is you or the upcoming backpack hero.
i did play your cat game though. for like 4 minutes. would i honestly rate it, i could not. if i were pressed, it would be 1 star, as it was not fun. waiting for three minutes to press all 3 buttons and then waiting another long time to go to sleep? i aborted when the cat appeared. that has to be packaged better to be intersting. i think 5 night at freddys accomplished that.
a breaking 4th wall jump scare game is just not my cup of tea. i have more fun writing this comment.
but ok, a short list what offends gamers:
games that set off the virus scanner, try to connect to the internet without reason, ask for admin permissions, write stuff where it does not belong, install additional stuff including stuff that stays in the system after deinstall, mess with system settings (like display, language settigns and what not), make them think the hardware is broken, aaand of course, all the snowflakes out there being offended by whatever they chose to be offended by today. and letting their anger out on small time devs giving them 1 star. (my lowest rating is 3 so far on itch. if a game does not interest me, why should i rate it. it would only mess up my recommendations ;-)
i do not know much about web games, but can a web game not be made look like it crashed or be made crash intentionally or at least exit gracefully? you can always try to trick people into pressing ctrl-w. i remember hempuli pulling that one of, by making a platformer with f4 as the jump key. and then introducing alt as a run key and having puzzles that need you run and jump. you can imagine what happens. and then the game has the audacity to chide the player for closing the game citing the risk of save game corruption.
or just make the player restart the game, because they think it is stuck. you can always branch off into a dead end, displaying repeating error messages. use some semi plausible techno jarble about stack overflows or whatever. you can make it interactive and include the user to press the exit button. you even promised such for this download game
If for anyone reason you are stuck somewhere and you can't interact with or close the game, press Alt + F4.
(clarification, i did not play your game. as such i did not have any problems. my latent concern is, that you need access to the computer to pull some stunts, like exiting the game. if that were the only thing, meh, just use a web version of a similar stunt. you will have more potential players. that's my 2 cents.)
