New Top-Down Engine I'm working on!

I'm working on a new Top-Down view fighting engine. I'm making it from scratch. Basically, you move with the arrow keys/WASD and you rotate your character using the mouse. Clicking the mouse allows you to swing your sword in a direction depending on your cursor's location. You can also use special abilities that have Cooldowns. After I complete the engine I will probably turn it into a game. With upgrades/items available for purchase in the shop!
