Thank you a lot for the feedback guys.
@UberLou: Interesting thoughts.
The dodging wasn't implemented yet in day 3 prototype, I made it so that you dodge by moving the mouse on the left/right axis between the moment the opponent is arming (atm though, the arming is not visually signified yet) and shooting (the flash appears).
I'm planning on some tutorial to have a better apprehension/training of the dodging mechanic (and the opponent will also have a dodging mechanic).
Perhaps you're right about the pulling, it's also true that I tend to "push up" my mouse too "intuitively" when I draw. Perhaps it would be indeed better to skip the mousewheel up part and simply have the gun showing as soon as you have drawn, allowing you to focus on the aim/arming of the gun.
For a minigame/reward on a perfect draw, that's an interesting idea, I'm not sure yet how to put that in though (as well as what consists of a perfect draw, since "all you have to do" is to roll the mousewheel down quickly). Perhaps it could just appear as a bonus $ once the duel is over.
@GenkiGenga: I'm planning on having some tutorial part to learn better aiming, at your own pace with a fixed mannequin that won't shoot at you.
A crosshair was already suggested by another tester, but it doesn't feel well. The aim comes from the nose of your gun and the angle of the arm/pistol. Adding a crosshair that follows the mouse is kind of confusing in the end.
To make it feel better, I've already relocated the arm when you pull the gun so it appears more in mid-screen, which feels better.
@valdarko: Unfortunately, being for a 7 day challenge and being in day 4 of that challenge, I feel it's too late to change the theme.
Also my goal was to capture the experience of a far west/western pistol duel, and I feel it's pretty much there. Switching the theme now would just end up in me not completing the challenge in time.
Thanks again for all your feedback !
