Thanks for your feedback, I really appreciate it!
Patti will be re-rendered, that's on the to-do list, so you've spotted that well. Thanks for the reminder about sound effects. That somehow got a bit forgotten in the production, although we actually have the sound files ready, so we'll add that soon.
The time travel story is explained in detail in "Sweet Science", the previous game (in a different branch of that story which does not lead to the events in "Kieta Memory"), so instead of a lengthy explanation we cut it short in the intro. There will be more mystery about that later...
Regarding the first choice... Interesting point. We thought, on the other hand, the first choice should be an easy warm-up instead of something really decisive.
