Hello, thanks for the detailed feedback!
As we've mentioned earlier, keyboard controls were cut out not so long ago because they caused plenty of bugs. It's temporary and doesn't reflect how the game is intended to be played. All shortcuts and hotkeys will be added to the game as soon as we fix the aforementioned issues.
Your quality of life suggestions make sense, I'll write them down.
Speaking of writing, it's mostly translation issue. Cutscene dialogues weren't proofreaded by the native speaker, because they were alredy voiced by that time, but the rest of the game (e.g. item and skills description) is pretty much final. Did some of those still feel like a placeholder?
Red shields reflect stat penalties because of item's low durability.
Modes are in a very early iteration currently. They will be improved in the future. Items drop out because our game currently doesn't have any save system, so it's temporary as well. Changing mouse cursor in FOW is a known bug, we'll fix that.
