Turn Depths
Every step you take burns a turn — kill monsters to refill them and reach floor 30.
Swipe to move one tile in a top-down dungeon; each move drains the turn meter, bumping an enemy refills it, tap to swing sword or hold to aim projectile.
One-thumb swipe to move, tap to melee, hold-to-aim-and-release to shoot.
Cursed-cave roguelike loop from Broken Depths RPG with the strict turn-economy.
Broken Depths just dropped with 5.0 stars and the GMTK Game Jam visibility is peaking.
Broken Depths RPG by sirmilkman is a real GMTK 2026 jam submission whose pitch ('turn based roguelike, only a few moves to reach the exit, floor 30') is identical to this concept — the trend anchor exists, but it's a jam game with only 149 ratings, not yet a chart-topping mobile hit.Jam page confirming 'Broken Depths RPG' premise matches Turn Depths almost verbatim ↗Dev page for the source-of-inspiration jam entry ↗
Roguelike/dungeon-crawl mobile games have proven streamer/clip appeal (Slay the Spire, Vampire Survivors, Dead Cells), and a one-thumb swipe + visible turn meter is highly TikTok-friendly — but the sub-niche is small vs. broader hypercasual.List of dominant mobile roguelikes showing the genre already has viral hits to benchmark against ↗Late-2025 vertical-roguelike guide underscoring mainstream visibility of the format ↗
Top-down tile grid, swipe-move, tap-attack, hold-aim are all stock Unity/Godot patterns; procedural floor 1–30 with simple monster AI is a weekend-prototype scope.
Hypercasual is still strong (2.4B downloads / $345M IAP in H1 2025), but ad-heavy formats (interstitials, rewarded video) perform best on puzzle/match — dungeon/roguelike skews toward IAP/meta-progression, so this idea fits the model only partially (revive-token rewarded videos).H1 2025 hypercasual top-100 = 2.4B downloads / $345M IAP — opportunity exists but category fit is mixed ↗Ad benchmarks: puzzle/match lead interstitial & rewarded-video revenue, not dungeon/roguelike ↗
Mobile dungeon-crawler and roguelike space is clearly crowded — Slay the Spire, Dead Cells, Vampire Survivors, Downwell, Crypt of the NecroDancer, plus Soda Dungeon, Enchanted Cave 2, RogueSlide and many more; the 'turn-meter refilled by combat' twist is small differentiation in a packed category.33 best mobile dungeon crawlers listed — category is mature and saturated ↗RogueSlide is essentially the same swipe-to-move, tile-based, turn-based dungeon hook already shipping on mobile ↗
