# Turnfall

> ResidualPlay case file: an overlooked Steam game still earning residual revenue. Estimates carry a ±30-50% error range per title.

- Steam appid: 3764420
- Developer: Koleapin Studio
- Released: 2025 · Genre: Adventure · List price: $39.99
- Deal grade: A (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $14.1k to $21.1k per month (mid $17.6k)
- Opportunity score: $32.6k/month at x1.85 dormancy multiplier
- Est. lifetime owners: 3.2k · Est. lifetime net revenue: $42.9k
- Review sentiment: 95% positive across 101 reviews (100 from Steam purchases)
- Review velocity: 52.5 reviews/month (6-month average)

## Why it's flagged

- No developer announcement on record, ever
- Studio quiet across its whole catalog
- Last build shipped 15 months ago
- Store page localized in only 1 language(s)
- Last discounted 7 months ago, 4 sales in the last 12 months

## Where a gross dollar goes (monthly, at current velocity)

| Stage | USD/month |
|---|---|
| Gross storefront sales | $32.0k |
| After VAT / sales tax (-13% blended) | $27.8k |
| After refunds (-9.5% median) | $25.2k |
| Net to developer (after Steam 30%) | $17.6k |

## Monthly review counts, oldest to newest (2 months)

99, 6

## Missed seasonal-sale revenue (modeled)

Skipped 2 Steam seasonal sale window(s) in the last 2 months. Running a -50% discount in those windows is modeled at +$17.6k net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Estimated acquisition range

$422.4k to $844.8k (2-4x the trailing net annuity of $211.2k/year). Same error range applies.

## Markets by review language

- english: 61%
- russian: 39% (game NOT localized in this language)

Localization gap: 39% of measured reviews are written in languages the game does not support (top: russian). Localizing is likely immediate market expansion.

## Analyst notes (AI-assisted)

Turnfall is a turn-based tactical puzzle-adventure where a knight navigates deadly grid-based labyrinths filled with traps and enemies, requiring careful planning and resource management to survive.

Turnfall has shipped 3,200 copies and earned $42.9k lifetime on a $39.99 price point, generating $17.6k/mo residual revenue with 95% positive reviews and a 52.5 review/mo clip. The game is dormant post-launch (6+ months since last discount, developer inactive) but the core audience, tactical puzzle enthusiasts and retro dungeon-crawler fans, demonstrates strong word-of-mouth and engagement depth (median 3h playtime on positive reviews). Revival or light publishing support could unlock the 39% localization gap (Russian-speaking market underserved) and the $32.5k/mo upside opportunity, though control feel and difficulty balancing remain contentious.

- Most realistic play: revival
- Risk (tech): Two negative reviews cite slow character reactions and janky feel; control responsiveness is a known friction point that may cap ceiling without gameplay rebalancing.
- Risk (market): Niche audience (turn-based tactics + arcade intensity hybrid) limits addressable market; mainstream positioning has never gained traction (mainstream flag: false).
- Risk (other): Developer is fading (studio_status flag) with only one title and no community posts in 6+ months; revival requires external resource commitment or acquisition of IP and code.

What players are asking for:
- Control responsiveness and input timing refinement to match arcade expectations
- Difficulty calibration: clearer trap telegraphing and less punishing early levels
- Localization into Russian and other major languages to unlock regional growth
- Quality-of-life features (settings, accessibility) to broaden appeal beyond hardcore

Suggested first moves:
1. Acquire IP, source code and perform 4-6 week control/input lag audit; test revised build with 20-30 tactical puzzle veterans to validate responsiveness fix before re-launch.
2. Commission Russian localization (39% loc gap, 39 Russian reviews already posted) and soft-launch in CIS markets with modest discount promotion ($9.99 for 2 weeks) to test elasticity and validate upside opportunity.
3. Negotiate publishing partnership with indie tastemakers (e.g., Humble Games, Devolver Digital community arm) to re-market to turn-based strategy / roguelike communities and capture organic review velocity (currently 52.5/mo baseline).

## Methodology

Units are estimated from Steam-purchase reviews times a release-cohort multiplier (Boxleiter method, 20-75x by year). Revenue uses an effective price (lifetime discounts and regional pricing) and nets out VAT (~13%), refunds (~9.5%) and Steam's 30% cut: roughly 55% of gross reaches the developer.
