AllSims Mod
Updated for game version:
0.3.2 (The way the mod is coded, even if the current game version is ahead of the mod, the mod will still work & not create problems. You just won't have any changes to the game content past this version. With the dev saying there won't be any 'choose 1 sim only' choice past version 0.2.1, the mod can be considered complete. I'll still try to update it to adjust the dialogue, but it shouldn't be any problem playing with an outdated mod
unless the early content gets changed of course)
Features: Play all the sims in one play through naturally. (more info in spoilers)
Installation: Drop the 00_AllSimsMod.rpy file in the /game folder (found where the.exe is present)
Works with existing saves (more info in spoiler)
Doesn't break saves.
Seems the dev went with the 'see only 1 out of 3' format for the sims.
Looking at the game's story, there shouldn't be a problem even if you see all the sims in one play-through.
Hence the AllSims Mod let's you, the player, decide whether the mc tries to see more than 1 sim per opportunity.
To the dev:
dev check the indent on line 9298 in script.rpy.
It seems to be locked behind the final else when it should (probably) be outside the if-else structure.
