- Developer: Turtle Stack Games
- Released: 2025 · Genre: Indie · List price: $6.99
- Deal grade: C (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $3.0k to $4.5k per month (mid $3.8k)
- Opportunity score: $3.8k/month at x1.00 dormancy multiplier

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $6.8k |
| After VAT / sales tax (-13% blended) | $5.9k |
| After refunds (-9.5% median) | $5.4k |
| Net to developer (after Steam 30%) | $3.8k |

## Monthly review counts, oldest to newest (15 months)

68, 126, 104, 89, 68, 55, 102, 125, 110, 68, 57, 81, 73, 42, 63

## Missed seasonal-sale revenue (modeled)

Skipped 4 Steam seasonal sale window(s) in the last 15 months. Running a -50% discount in those windows is modeled at +$12.9k net in total, assuming a unit uplift of x3.0 (industry-typical for old catalog titles). Same ±30-50% error range applies.

## Markets by review language

- german: 2% (game NOT localized in this language)
- english: 81%
- russian: 15% (game NOT localized in this language)
- spanish: 1% (game NOT localized in this language)
- schinese: 0% (game NOT localized in this language)
- brazilian: 1% (game NOT localized in this language)
- french: 0% (game NOT localized in this language)

Localization gap: 19% of measured reviews are written in languages the game does not support (top: russian). Localizing is likely immediate market expansion.

## 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.
