Big steps to making the game a real game

Changed the name of the project to King of wars

Upgraded hp bars to 10k, added collisions with castle check and fire projectiles for both player and enemy.

Added Wave linked to timers which I'm thinking to link them to either spawn faster or spawn more on certain waves.

Changed the gold cost of units and fixed the gold going below 0 when buying units.

Thinking about adding upgrade cost for castle for more hp and maybe build up the castle or just display a level of it

Also adding towers building to buy would be a good next step for me.

Special button summons meteors if needed but i should make it an unlockable eventually.
