Thank you for your feedback, that's what we need to improve our game even further. To answer some of your questions:

Yes, there's a penalty for not pushing space during the obstacles, although it's quite trivial at the moment, every obstacle you don't pass decreases your strenght a little and when you have to concentrate during the javeling throw, less you have the strenght left, harder it is.

Maiden's stage is still under the construction, yes. And there's supposed to come a game over situations for both of our characters.
