Game Type: Top down shooter/Roguelike shooter.

Level ideas: A level with randomly spawning enemies, randomly generated rooms (kinda like in ¨the binding of isaac¨) with entrances and exits, An infinitely
generating floor with randomly generated props (what i mean by ¨randomly generated props is, im gonna make some props and then the props are gonna be placed in random locations on the map) and enemies.

Art: 2D(Pixel-art) or 3D(low poly)

Mechanic/ideas: player levels with upgrade points that can be spent on upgrades like more ammo, health, movement speed, vision lenght. Etc

Enemy ideas: Zombies that follows the player in hords making it dificult for the player to get away. An enemy with ranged attacks, maybe a wizard or a zombie wizard?

Boss mechanic ideas: Boss rooms will be generated (this is if i choose to make randomly generated rooms like ¨the binding of isaac¨ ) or Boss spawns after a number of waves (if i choose to make the game on an infinite floor with randomly generated props and enemies)
