Yup, although it doesn't show a lot in the demo:
- every skill test you perform and for some action, you win a small skill boost for every future action.
- depending on the action, the permanent boost is more or less important
- depending on the action, there is a cap to how much you can increase your skill with said action (you won't be good at a game just jumping over the ennemies in the first screen)
For example if you fail on the first boss again and again, each time you will have better odds to shoot correctly, even if you don't save the game. I could have done without this mechanic, but in case I expand on the game I think it will be important for a smoother experience.
