Twin stick shooter built in unity

This Project is mainly intended for me to learn how the unity engine works. The goal is to build a functional twin stick shooter with the following features from scratch.

Primary Features : - Twin stick movement and shooting gameplay - Enemies spawning in waves with increasing difficulty - Multiple enemy types (like 5 maybe?) with different behaviours - Upgrade system for player - Score for eliminated enemies - Main menu with basic functions - Sound effects and music (not including making sound and music itself) - Particle effects (impact, explosions etc.)

Secondary (optional) Features: - Scoreboard - Synergistic weapon upgrades / projectile changes (e.g. beam, seeker missile etc.) - Shop mechanic where player can buy health/ upgrades etc. for points in between waves. - Boss enemy

Used software: Engine: -Unity3D sound: -Bfxr (http://www.bfxr.net/) Modelling: -Autodesk Maya Sprites: -Gimp
