Alien Survival 2D

Hi all!
This is my first project and after a month of hard work, I am proud of this playable version of AS2D! I am mainly looking for feedback here, thanks in advance! The game is inspired from CoD Zombies; it is a round based survival game where you build up your arsenal to fight off the incoming aliens - who get stronger every round. GAME CONTROLS: T to swap weapons, Left Mouse Button to shoot, F to interact, WASD/Arrow Keys to move, ESC to pop up the menu.
