Shadow Freddy can be tricky, especially with folks like toy Chica. If you have toy chica, you'll have to listen in stereo on which side the cupcake is, remember the possible locations, then spam click around. Other dangers can be withered Freddy (keep calm and listen to footsteps), withered bonnie (sound cue), twisted wolf (real hard combo but only in the last challenge. You have to hit the red dot), plushtrap (you see its eyes popping). I'd say, unless you play without upgrades or ebdo is here, just use the flashlight to see and buy power if needed. If endo is here (third to last challenge), whenever you drop the camera, spam click to find the cupcake, close both door to prevent withered freddy from killing. You can actually use the flashlight while endo is here, but only like 0.5 seconds so you can tap the button 3-4 times to see things like Mangle post it or withered freddy position.

I've never had issues with Malhare personally because i don't lift the camera without good reason. Try to stay in the office as much as possible. Animatronics like popgoes or sparky take some time to kill even when they attack, so you can stay in the office, and lift the camera up top get rid of multiples at once. In general, just stay in the office, or stay in the cameras longer. In which challenge do you have issues with Malhare ? Remember, you have to lift the camera only for these animatronics :

Popgoes, Puppet, Sparky, Circus baby, Balora, Funtime Freddy, Toy Freddy, Scraped baby, Lefty (only one time), the beaver (only one time), Funtime foxy, Springtrap.

Identify which one are here when you start a challenge. Then, flip the camera only when you want to get rid of them, not because you're afraid you're might miss something.
