Now, a criticism of Encased much more solid than "excessive amount of lootable containers" is the combat. The game says outright that fights are balanced around having a party backing you. Guess what you don't have during the prologue? Of course, that just makes you seek alternate routes and means, but some quests are just unbeatable because giant cockroaches are like that as well. On the other hand, this might result in this "replayability" things, something that stuff like modern The Elder Scroll entries lack by making everything accessable to any character.
