# Lifeguard Holic > ResidualPlay case file: an overlooked Steam game still earning residual revenue. Estimates carry a ±30-50% error range per title. **Measured on 2026-09-18 22:59 UTC.** The whole Steam catalog is re-measured daily; a game that just launched can move a lot between passes. - Steam appid: 4090260 - Developer: Tiramisu - Publisher: Mango Party - Released: 2026 · Genre: Casual · List price: $16.99 - Deal grade: C (A = dormant with >=$5k/mo opportunity, D = low signal) - Est. net residual revenue: $23.1k to $34.7k per month (mid $28.9k) - Opportunity score: $28.9k/month at x1.00 dormancy multiplier - Est. lifetime owners: 8.1k · Est. lifetime net revenue: $46.3k - Review sentiment: 93% positive across 211 reviews (203 from Steam purchases) - Review velocity: 203.0 reviews/month (6-month average) ## Why it's flagged - Developer active, last post 0 months ago - Studio active elsewhere (3 titles tracked), so this one may welcome a partner - Last build shipped 0 months ago - Last discounted 0 months ago, 1 sales in the last 12 months ## Where a gross dollar goes (monthly, at current velocity) | Stage | USD/month | |---|---| | Gross storefront sales | $52.5k | | After VAT / sales tax (-13% blended) | $45.6k | | After refunds (-9.5% median) | $41.3k | | Net to developer (after Steam 30%) | $28.9k | ## Markets by review language - english: 15% - koreana: 14% - russian: 7% - spanish: 5% - schinese: 58% - brazilian: 1% (game NOT localized in this language) ## Methodology Units are estimated from Steam-purchase reviews times a release-cohort multiplier, 40-75x by year. Cohorts from 2020 on are calibrated against 182 sales milestones announced by developers; older ones follow the published Boxleiter tables. 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.
