(Strategic Takeaway) {#so-what} Galaxy Invader - Alien Shooter is a games app that is free with in-app purchases. It holds a 4.75/5 rating from 69 reviews. > **Bottom Line:** Restoring the ad-removal purchase flow is the only way to stop the current erosion of user trust. If the billing integrity is not addressed, the app will continue to lose its casual player base to more reliable, actively maintained competitors. **Best for:** Casual gamers interested in classic arcade-style space shooters and progression-based combat. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit the ad-removal purchase flow because users report paid features are not honored → restore user trust ### Feature Gaps vs Competitors - Competitive multiplayer modes (available in Galaxy Attack: Alien Shooter but missing here) ### Outlook: Declining The arcade shooter market is consolidating around live-service titles that offer frequent content updates and social features. Galaxy Invader - Alien Shooter remains in a maintenance-only state, which leaves it exposed to rivals that can better sustain long-term engagement, ultimately leading to a decline in active users. - 🔴 The three-year update gap prevents the app from matching the live-service cadence of rivals, which accelerates player churn toward more active titles. - 🔴 Users report: Broken ad-removal purchases create a perception of deceptive billing, which directly compresses the conversion rate for any future monetization attempts. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.75/5 | | Total Reviews | 69 | | Sentiment | Frustrated (40/100) | | Confidence | Medium | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Galaxy Invader - Alien Shooter** (this app) | 4.75/5 | Frustrated | Mai Duc | | [Pulsar](https://marlvel.ai/apps/pulsar) | 4.9/5 | N/A | Afterburn Lukasz Spierewka | | [Save The Earth.](https://marlvel.ai/apps/save-the-earth) | 4.5/5 | N/A | Ca Li Sa | | [Super Pixelander](https://marlvel.ai/apps/super-pixelander) | 4.5/5 | N/A | Sunny Tam | | [Cave FRVR](https://marlvel.ai/apps/cave-frvr) | 4.5/5 | N/A | FRVR | | [Planet Defense - Protect Your Solar System](https://marlvel.ai/apps/planet-defense-protect-your-solar-system) | 4.3/5 | N/A | Rory Buckley | ## Company Profile - **Developer:** Mai Duc - **Website:** [https://galaxy-invaders-f7791.web.app](https://galaxy-invaders-f7791.web.app) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/galaxy-invader-alien-shooter/id1530764221?uo=4) - **Dev Site:** [Official Website](https://galaxy-invaders-f7791.web.app) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Pulsar*](https://marlvel.ai/apps/pulsar) (Afterburn Lukasz Spierewka) · 4.9/5 Rating - [*Save The Earth.*](https://marlvel.ai/apps/save-the-earth) (Ca Li Sa) · 4.5/5 Rating - [*Super Pixelander*](https://marlvel.ai/apps/super-pixelander) (Sunny Tam) · 4.5/5 Rating - [*Cave FRVR*](https://marlvel.ai/apps/cave-frvr) (FRVR) · 4.5/5 Rating - [*Planet Defense - Protect Your Solar System*](https://marlvel.ai/apps/planet-defense-protect-your-solar-system) (Rory Buckley) · 4.3/5 Rating - [*Rock Blast*](https://marlvel.ai/apps/rock-blast) (Beijing New Vision Real Estate Development Co., Ltd.) · 5.0/5 Rating - [*Smash Rocket*](https://marlvel.ai/apps/smash-rocket) (STORMX) · 3.5/5 Rating - [*Space Shooter: Galaxy Invader*](https://marlvel.ai/apps/space-shooter-galaxy-invader) (Anh Nguyen) · 4.9/5 Rating - [*Hop Skip Rush Tap to Jump*](https://marlvel.ai/apps/hop-skip-rush-tap-to-jump) (MDBTDJ) · N/A Rating - [*Space Fight Rush - Hyper Play*](https://marlvel.ai/apps/space-fight-rush-hyper-play) (MDBTDJ) · N/A Rating ## Frequently Asked Questions {#faq} ### Is Galaxy Invader - Alien Shooter worth paying for?
