Thank you for your feedback!
The controls in general seem to be a challange to a lot of people and not as intuitive as I had hoped. I plan to add better feedback to the player as to what they might be doing wrong.
I like your suggestion of keeping moves on the screen!
As for your analog stick suggestions:
Right now I feel, that the analog stick is not precise enough, but I'll keep your idea in mind and will keep experimenting.
When you say "snake strike", do you mean this? 
I also think, that this still needs a way better explanation and more feedback to the player. I already have something in mind here.
I will do a devlog once I implement the changes. Would be cool, if you could give me feedback then again!
Cheers :)
