In the World Tournament Stage, your character floats over the ground around the arena instead of physically touching it. Why is this? Because in the source material, touching the ground means you lose the match.
The player character can't wish for immortality, which makes some sense as in DBZ it's something of a character alignment thing to actually desire immortality, but it seems odd you can't use the dragon to wish for something similar to help you patrol. Thinking about, though, it would make sense if the characters already had a form of immortality because even though they can get knocked out it's impossible for them to die. It's quite possible the Time patrollers, or at least those deemed important, get a wish of immunity to fatal blows so the Time Patrol never needs to worry about losing members on mission.
Likewise seeing certain characters such as Videl and Android 18 wear special custom bikinis and how they react to them is rather on point, since neither female had much if any Ms. Fanservice moments in the canonical series note Android 18 had her original Red Ribbon Army clothes getting destroyed by Vegeta in her first fight in the Android Saga which gave viewers a gratuitous Panty Shot (though hard to see), her breasts getting groped by Master Roshi during the Buu Saga and her clothes getting wrecked again during the Super 17 Saga that had part of her bra on full display and even a bath scene during GT. Videl likewise had a Leg Focus shot in her debut appearance and got her breasts poked by Roshi after she's revived: Videl is highly embarrassed to wear her bikini but rolls with it anyways since she thinks it's part of her training, Android 18 on the other hand is batshit livid with her's but wears it anyways out of respect though not before letting the Time Patrollers know how disgusted she is with them, knowing very well that Master Roshi and Old Kai are likely peeping on her in battle.
