I encountered a couple of bugs, so I thought I'd report them:
1) When two party members are eaten, a party member whose health is reduced to 0 can still act as normal as long as the occupant they're sharing the stomach with is alive
SPOILERS AHEAD
2) Against Da Boss, if you drop her to 0 health with Lana Da Boss will trigger the cutscene where she eats everyone, but the turn continues as normal so if any of your other characters are attacking you just defeat her and skip the "escape her stomach" part entirely
