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 with 12 to 15 waves each, from a quiet meadow to 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 waves that never stop. Daily Siege: a new siege every day, the same for everyone.

Built for touch: tap a stone, tap a tower. Works on desktop and on phones held sideways. Progress is saved.
