Reading the rules for the Last Survivor I consider that the following points should be improved:
1. Creating your survivor: In this section you should extend each section, for example that you don't have a buddy or a rival. (An example of how I feel these sections should be extended would be what you did with the Strider Mode supplement for One Ring, the section of Your Adventurer leaves no doubt).
2. Adding examples in each section following a mini adventure would be excellent for new solo players since at first, the use of each timer, table and encounter is confusing (at least I had to read everything for an hour repeatedly before I could start playing)
3. Since the stress and panic tables are going to be changed, comment what would be the new tables for the solo mode.
