Thanks for your comment!
Some of the problems you mention, such as the change of direction in the air, have already been fixed after the demo.
What you say about the signals is something that I have been thinking about changing for a while. Intuitively people tend to press the A button to interact, but it's definitely annoying at times to jump.
Regarding the archer, since there are six characters I try to maintain a balance between all of them without any of them being overpowered. The final settings will possibly vary a bit from the demo.
Thank you very much for taking the time to play the demo in depth and do this detailed analysis.
I hope you enjoy the final game!
