- Developer: TheBigO Games
- Publisher: EroBits
- Released: 2026 · Genre: Adventure · List price: $5.99
- Deal grade: B (A = dormant with >=$5k/mo opportunity, D = low signal)
- Est. net residual revenue: $271 to $407 per month (mid $339)
- Opportunity score: $542/month at x1.60 dormancy multiplier
- Est. lifetime owners: 864 · Est. lifetime net revenue: $1.7k
- Review sentiment: 91% positive across 33 reviews (27 from Steam purchases)
- Review velocity: 6.8 reviews/month (6-month average)

## Why it's flagged

- No developer announcement on record, ever
- Studio active elsewhere (8 titles tracked), so this one may welcome a partner
- Last build shipped 10 months ago
- Store page localized in only 1 language(s)

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

| Stage | USD/month |
|---|---|
| Gross storefront sales | $615 |
| After VAT / sales tax (-13% blended) | $535 |
| After refunds (-9.5% median) | $484 |
| Net to developer (after Steam 30%) | $339 |

## Monthly review counts, oldest to newest (4 months)

24, 1, 1, 1

## Estimated acquisition range

$8.1k to $16.3k (2-4x the trailing net annuity of $4.1k/year). Same error range applies.

## Markets by review language

- english: 93% (game NOT localized in this language)
- schinese: 4% (game NOT localized in this language)
- brazilian: 4% (game NOT localized in this language)

Localization gap: 100% of measured reviews are written in languages the game does not support (top: english). 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.
