Spinner Defender gets a first update published.

This was a tough one, the update took a while for having to learn how to implement the new kill counter with proper functional UI and the fact that this was worked on and off whenever i could. 

To simplify testing for users on different OSes
The Updates will be pushed through the Web build of the game, downloads will be updated when the game reaches a more "complete" state

But here it is, small changes for now but things are starting to take shape a bit more, here is the changelog :

Changelog Postjam v0.1

- added a kill counter to track how many ennemies the player destroyed

- changed the collisions, the enemy hitboxes are a bit smaller, and the attack hitbox is a bit more precise to match what's on screen
