Glowkeep

Foes come out of the dark along the paths to your keep. Build towers on the stones beside the path: every tower lights the night around it, so you always see what it can reach. Shades hide in the dark until a lantern finds them.
- Four towers, two paths each. ARCHER (fast, hits flyers) becomes LONGBOW or VOLLEY. LANTERN (slows foes in its light, and it's the only thing that reveals SHADES) becomes BEACON or SUNFLARE. MORTAR (area damage, ground only) becomes BOMBARD or CLUSTER. STORM (chain lightning that ignores armor) becomes TEMPEST or FROSTCOIL.
- Nine kinds of foes. Grubs, fast skitters, armored brutes, moths that fly over mortars, shades that hide in the dark, splitters that break into two, wardens that carry shields, the Gloom Ogre, and the Gloom King himself.
- Two spells. FLARE lights an area, damages and reveals shades. ROOTS hold foes in place.
- Call waves early for bonus gold. Sell towers for 70 % back.
- Eight maps, 12 to 15 waves each: a meadow, a river with two gates, a long gate road, a fen with a flyway where moths cut straight across, a crossing with three entrances, a long barrow road that winds in to the keep, a mountain pass with two flyways, and the throne of the Gloom King. Earn up to 3 stars per map and spend them on six permanent upgrades.
- Endless mode. Win Hollow Gate to unlock it: waves that never stop and keep getting stronger, with an ogre every 10th wave. Your best wave is saved, and every 5 waves of a new best earn a star (up to 6).
- Daily Siege. Win Willow Meadow to open it: every day a new siege with 12 fresh waves and an ogre at the end. Win it on following days for more stars.

How this game was made: Glowkeep was made by AI agents at Crewless Games, a small studio where AI agents do most of the work and a human owner decides what gets released. The code was written by AI. There are no image or audio files: the towers, foes and scenery are vector (SVG) illustrations written as code by AI agents and drawn with the HTML canvas, the night lighting is computed in code, and the sound effects and music are synthesized in code. No AI image or music generators were used, and no third-party art.

The game is a fantasy tower defense strategy game where you protect your keep from waves of enemies emerging from the darkness. It combines tower placement, defensive upgrades, spellcasting, and tactical planning.

Build towers on designated stones beside enemy paths to attack incoming foes. Each tower provides light that reveals its attack range, while Lantern towers and the Flare spell help expose hidden Shades. Use Roots to hold enemies in place, upgrade towers, and manage your defenses to stop enemies from reaching your keep.

The game focuses more on strategy. You must choose the right towers for each location, consider enemy weaknesses, manage your gold, and decide when to use spells. Different enemy types require different defensive approaches, making tower placement and upgrade choices important.

Yes, you can unlock different tower upgrade paths, permanent upgrades, and additional game modes. There are eight maps to conquer, with up to three stars available per map. Winning Hollow Gate unlocks Endless Mode, while completing Willow Meadow unlocks Daily Siege.

Yes, the difficulty increases as you progress through the maps and encounter more dangerous enemies, including armored brutes, flying moths, hidden Shades, splitters, and powerful bosses like the Gloom Ogre and Gloom King. Endless Mode offers an even greater challenge with increasingly difficult waves that never stop.
