Invade the aliens secret base!

You've been sent on a suicide mission for literally no reason. Invade the aliens secret base and find out what they're up to, or don't, I'm not a lawyer. Trawl your way through several shoddily put together rooms, fight a total of 3 (WOW!) enemies, and fight a total of 1 (WOAH!) repeated mini boss and 1 (CRAZY!) main boss. Receive upgrades from every mini boss you kill in hopes to find out just WHAT is behind that big red room. (it's a boss)

Features

• At least 1 enemy
• At least 1 room type
• At least 4 colours
• At least 1 mini boss
• At least 1 boss
• An ending (it's not funny)
• An intro (it's not funny)
• Credits (they're not funny)

Super important notes:

This is a simple project written as my second ever C++ project. It first started life as a university project before being polished. It's considered feature complete and is provided as is. It's quite rough around the edges, and must be played maximized for the mouse to work correctly.

Controls are WASD to move, mouse and left click to aim and shoot, escape to pause. Escape skips the intro.
