This is Sanguine, a procedurally generated bullet-hell rogue-like. It has multiple stages, randomly generated levels, upgrade pickups and a final boss.
I made this for the Mini Jam 118: Vampires jam on itch.io over 3 days, by myself and one other student.

The elements I created for this project included:

• Runtime procedurally generated levels
• Pixel art for levels, UI, Items, player character and final boss
• Player movement and combat
• Item pickup and stats system
• Main menu UI and HUD UI code
• Difficulty scaling and balance
