Playing Limbus Company With Only One Sin Affinity

I wanted to come up with a challenge run that was engaging and had at least some team-building aspects still in it. Here are the rules I came up with:
1. You may only generate 1 unique Sin Affinity for the entire run.
2. You may only use EGO Gifts that match the Sin Affinity you chose.
3. All Identities must be at Uptie Level 4.
4. No healing at Rest Stops or Shops.
This is probably the most difficult thing I've done in Limbus Company. Feel free to change the rules to make it more fun for yourself!
