I just finished the bow quest-line and thought it was time to give some feedback. The game looks absolutely gorgeous but is quite buggy (as expected.)
Bug list:
- Bow clipping through players leg
- Camera glitching out pointing or focusing in the wrong direction in conversations
- Limbs disappearing when equipping/unequipping clothes
- Peasant girl’s eyes disappeared during conversation (2spooky)
- People not sitting correctly on chairs (clipping through or sitting in mid-air like a magician)
- Reflection in the river is a purple texture
- Sometimes player cannot open doors, NPC interacting with it seems to fix it
- Sometimes during the shooting competition the player does not receive a bow
- Sometimes you to get stuck in conversations, a new game is required
- The backface of clothing is invisible
- Using the cl_fov command at higher values causes some clipping with the characters shoulders
Those are the ones I remember from the top of my head, but there are still other issues that may or may not be bugs:
- Aiming with a bow feels floaty (probably going to be better as the character progresses)
- Bow animations and sound effects does not feel satisfying at all
- Conversation window takes up too much space on the screen
- Conversation window is not fully mouse-driven (at least I didn’t figure it out)
- Foliage is too dense, would like to see a foliage density slider for people with weaker systems
- Head bobbing causes motion sickness, especially combined with the low default FOV
- Lots of missing options in the graphics menu including FOV (currently you have to use console commands)
- Needs key-rebinding and more keys like a hold to walk, crouching ETC (no doubt it will be added anyway)
Looking forward to the next update
