TL,DR: cool looking, but does not appeal to my modern sensibilities.
I'd like to enjoy this game, but it's like reading an old book. The visuals and animations are awesome (if not a bit too blurry), and the skills and scenarios are interesting, but everything else is so slow and... as if made to waste your time. Walking to anywhere takes ages and encounter rates feel too random (no spawns when you want to farm).
Games about surviving a harsh environment can be fulfilling, but not particularly fun. And on a game jam I don't think that's what you want to do. 30 minutes in and the only thing I accomplished was killing random skeletons and wasps just to pay for my healing, and getting some nice equipment. Doing trips from the village to the cave, killing 10~15 guys and going back to sell parts and heal, over and over, is not enjoyable.
I might play more later. The mood (aside the world map) is fitting and the music and first-person animations are very cool. Seems immersion is a big focus here, and . But I can't be fussed right now, got stuff to do, games to play. If Blade User is going to disrespect me with movement slow as molasses and grinding just to make a living, I'll disrespect it as well. Sorry, and take care.
