Thanks for trying the game and for the feedback. About the movement I noticed the most of people prefer snap turn instead of smooth rotation.
The goal of the game was to search and find the places where you had to bring the packages, and those places were signed with a cone of light, you also have to be quick and avoid the enemies cause they can beat you easily, the use of shuriken is just in case of emergency If they are really putting you in bad situation. so that's the concept of "express" and "silent delivery" of the title.
I intentionally limited the rocket power and the grappling usage because I wanted people to explore and use the grab system too, otherwise I would use only them and the game wasn't fair.
