I'll switch to other games for now because I spent an entire afternoon on it and I want to play other games. I think I'm almost there, I've got the 3 flame parts, the hammer and the feather grieves, still wondering what I should do to get the good ending (in fact if there's no alternative ending then that you can tell me), whether it's linked to the skeleton, the corpse or something else.
The game is great, the control, perspective and movement are perfect, the dungeon is very good, I love the cartonny style of the skeletons and flames and the combat system is fun enough, I specially like how different equipment changes the bar.
