Alien Survival 2D

Hi all! This is my first project and after a couple months 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., though you also gain experience points which will increase your level, which will let you choose what you want to upgrade, and eventually lets you pick passive and active abilities.

GAME CONTROLS: WASD/Arrow Keys to move, T to swap weapons, Left Mouse Button to shoot,  Right Mouse Button/V to use melee weapon,  Space/Q to use active ability (once unlocked), F to interact, ESC to pop up the menu.
