In the Try Again screen for Air Rally, the dog character Baxter is shown in a falling plane. However, since the game can be played as much as the player likes, this is non-fatal.
Not trypophobic specifically, but if you're doing well during Launch Party, there will be lots of cartoony stars in the sky, which do overlap. (They could also cause eyestrain)
Not stabbed, but sliced. The demons in the Samurai Slice games are sliced in half by the Wandering Samurai, but it isn't graphic at all. Literally like scissors cutting paper.
In the Try Again screen for Air Rally, the cat character Forthington is shown in a falling plane. However, since the game can be played as much as the player likes, this is non-fatal.
You have to hit spiders away from yourself in the game Packing Pests; however, these spiders are perfectly fine, and only walk away looking a little dizzy.
In Fork Lifter if the player makes a 'barely' input where a bean gets trapped between two prongs of the fork rather than being pierced, the person offscreen will cough when they raise their fork to eat as though the unpierced bean made them choke for a moment, but they won't continue to choke afterwards.
However some games (notably Remix 10) have a fake-out ending only to surprise you with more action, which can catch you off guard. Missing a Perfect also causes an unsettling sound that can be anxiety inducing.
There are demonic creatures that the player must slice apart in the game Samurai Slice and its sequel that are made to look like ghosts. There is also an optional game called Sneaky Spirits in which the player shoots ghosts with a bow, though they are shown in the epilogue to be unharmed.
The game Fork Lifter has eating noises, including swallowing and chewing. There are also repetitive stepping, tapping, or clacking noises in multiple games, namely those that require you to keep the beat.
I wouldn't say so. The minigames are their own brand of Warioware weird (makes sense, since they're developed by the same people), but everything is otherwise grounded.
Missing a Perfect makes a sudden, loud, and very startling noise. The heart-pounding pressure of trying to hit every beat perfectly makes it much easier to be startled.
Working Dough and Samurai Slice are some of the games that have flashing lights. The games in Fever have more flashing than their re-releases in Megamix. Consider getting that one instead.
The characters in the introductory sequence speak directly to the player, as does the Barista in the Cafe. The characters from the intro also return after the player beats Remix 7.
Not man in a dress specifically, but Samurai Slice 2 features the samurai saving a toy bunny, shown to be for a little girl, from a horde of demons. He isn't ridiculed for this at all, iirc.
No active aphobia. But for my romance-repulsed folks, this might be a game to avoid. Double Date, Love Rap, and their sequels are all about romance, Bossa Nova has romantic undertones, the song for Karate Man is about a break up, and Remix 8's song is about some kind of romantic relationship.
An anecdote in game had MC Adore talking about how people mistake her car for being an actual alligator or crocodile (despite her car being pink), but no actual crashes are shown.
