Suggestion appreciated.

A few practical, tactical steps to complement the earlier replies from @coolpets, @Dani, @paulmarc and to answer @newageng's request for technical suggestions.

First, product and retention: map the new-user funnel and remove friction points. Make the first 2 minutes addictive — show a clear goal, give an immediate small reward, and unlock a visible next step. Instrument events for signup, tutorial completion, first purchase and first social invite; track D1/D7 retention, conversion to paying user, session length and churn by cohort. Use short A/B tests (one variable at a time) on the sign-up flow and the tutorial to see what moves those metrics.

Growth and promotion: build a community hub (Discord or forum), seed content creators with a tidy press kit and short playable demos, run time-limited events and referral rewards that give both inviter and invitee something useful, and repurpose clips or guides for social channels. If exploring paid acquisition, run small controlled tests across channels, measure CAC versus LTV, and scale only when ROAS is positive.

Technical checklist for a game site: minimize initial payloads and lazy-load nonessential assets, use a CDN for static content, add server-side caching and rate limiting, monitor errors and latency with real-time alerts, and keep frequent backups. Prioritize quick wins that you can measure in two weeks: onboarding tweaks, a single promo channel test, and one performance fix that improves load time. These give fast feedback and let decisions be data-driven.
