Gloomsday

Gloomsday is a dark roguelite action-platformer set in Colwell Academy, a magic school that has stood empty for over half a century. Thief Mora enters the school hoping to steal its magical artifacts, while Gary wants to prove he is not a coward. Inside, they find a sentient, sassy wizard’s hat, undead professors, crazed teaching assistants and invisible laboratory experiments with sharp claws. To break the academy’s curse and escape, Gary must embrace his unexpected magical potential and uncover the academic rivalry that shattered the school.

Explore Colwell Academy

The academy’s halls shift as you explore. Its mana hangs in the air rather than being tracked by a mana bar: casting drains the mana around you, and it slowly recovers when you stop using it. If you stay still, the world greys out, your spells fail and you die. Enemies draw on the same mana, so fights become contests for the available ground; you can drain a caster’s area or risk letting them drain yours.

Build your wizard

You can use 14 spells, including charged beams, channeled healing, wearable fire and summons that fight beside you. Glyphs, enchantments and pacts found along the way add to your build. Movement upgrades bought in the Grand Hall persist through deaths, gradually improving Gary’s limited thief skills. The combinations can produce builds such as a glass cannon, a tanky summoner or an invisible assassin.

Move and cast

Movement helps keep your mana flowing, and a double jump refunds spell charge. Tight platforming lets you line up casts, while the academy’s hazards can be turned against enemies. You can develop a rhythm of moving, casting and moving again rather than standing still.

Characters and bosses

Mora has a plan, while Hat—the talking hat—has suggestions. Some of the horrors in the academy’s depths begin to remember Gary, and friends and enemies alike have things to say. Bosses remember you between attempts, whether you win or lose.

Available content

The game currently includes the first region and its boss, along with the Grand Hall hub, a practice arena and dialogue that progresses with wins and losses. This content offers about 2–3 hours of play, with 14 spells, four enemy types and a miniboss.
