Thanks for all the feedback regarding the party/combat! It was kinda confusing that you couldn't start a fight if you put your spiders in the last slots, or that it wouldn't use your spider on the right most slot because it was only searching for the first 2 party members on the left.
Combat now uses your entire party, with a mechanic to slowly unlock more party slots
If I want to explore certain fights that force you to use only one single spider for the combat I might make it a separate feature from the main combat, definitely more of a mid-game thing with proper explanation on that. Probably call it something like "Solo Exploration"
You guys are great <3
