well a fun challenge is always
- 3 hearts
- no capacity upgrades
- broken giants knife
- no fairy upgrades besides magic and dins fire
- no lens of trurth
- 1 bottle
- no gold skulltula upgrades
- no dying
- no power crouch
- no hacks, glitches, or any cheats
- no using the megaton hammer except to stun volvagia and no deku sticks to attack people
- also if you want no advancing to the next map without killing all the enemies in the room your in except like hyrule field
I love doing that

then do it on masterquest...
its like doing a low lvl run in a rpg, it doesnt require skills, only preparation and being cautious
