Gridnova

GRIDNOVA is a top-down bullet heaven roguelike set on a neon digital grid. The player controls the Core, which fires automatically while the player moves through growing swarms of enemies, mini-bosses and bosses. Each level-up offers a choice of weapons and upgrades; pairs of weapons unlock synergies, and fully upgraded weapons can evolve into stronger forms. A standard run lasts twenty minutes, after which the player can continue into an endless mode where enemies keep getting tougher. Every week brings a new mutator that changes the rules of each run, along with a weekly challenge and online leaderboards.
