FULD is an FPS bullet hell with a lot of UI elements that you need to interact with and pay attention to at all times in order to play effectively.
It also has a weirdcore-esque aesthetic, using a combination of various images for most of its assets.
Currently, the game is infinite, with the goal being just to maximize your time survived and enemies killed, but there is also a Boss that appears after a certain number of kills.
The game will likely receive updates in the future that would add new enemies, bosses, etc.
