Is there any significance to the colored rocks scattered here and there? They seem to be posted in strategic locations and behind enemies, but I can't find a way to interact with them.

I think I killed all enemies in the epilogue after winning the game. Does this change something in the world? Hoped at least for a minor message. Maybe I overlooked a guy.

With the Ring of Skill as proof, I've set off to see how long it takes from start to get locked into a situation where you MUST take damage to win... didn't take long: the first bat you encounter REQUIRES that you take damage, because at LV3 you won't have enough ATT to one-shot them, nor enough DEF to nullify their damage....

Feels like I've been searching forever.

Hi, i know it's stupid but, i'm in the cell right now, there's something on the wall, the door is sealed, there is a table and a bucket and a bed but I can't do anything with it. So yeah, what I'm supposed to do ? thanks!
