Info about Protolife:

Official game description:
15 years since the first colonization parties landed on Gagarin-5. 15 years of tedious yet satisfying work on making this planet our home. I miss these years now.  
It all happened in mere days. The corruption spread across our lands, waves of crimson doom washed away our mushroom farms, and giant worms devoured our cities. As far as I know, only few thousands of people were able to escape into the emergency bases. Now the thing.. is dormant. It sleeps during the day, and grows only slowly over the night, filled with tumors, blights and rolling, nauseating pink lights.  
This small opening seems to be our only chance to fight back, to clean the planet. And we are sure to take it.
Gameplay
--------
Stand to defend a distant human colony against the growing lifeform that devours everything in its wake. Build complex defenses from the simplest element possible – a single block, save few remaining settlements and clean the planetary surface from the corruption in this original tower-based RTS. Initially built for a Ludum Dare 38 game jam, it was completely redesigned, got a graphics update, tons of new content, but still works around a simple idea: build towers from blocks, contain the enemy, survive the night onslaught and strike back.  
Key features
------------
*   Unique approach to building process: Every tower is constructed from patterns of simple blocks. Build your defense grid piece by piece the way you like it, upgrade, combine, optimize space and resources to survive against the overwhelming odds.  
*   An enemy unlike usual RTS adversaries: Growing, living entity designed to exploit every small weakness in your defense. The more space it takes from you, the more powerful it becomes.  
*   Freedom of strategy and flexible defense perimeter: Go for quick low-tier tower rush or bunk with well-defended artillery posts, then collect your blocks and rebuild the defenses on the spot — just mind the free space and resources left.  
*   Direct control over the builder: Or two? Dynamically switch between several battlefronts and dominate over the enemy.  
*   Over 30 levels with variative gameplay and win objectives.  
*   Random missions generator with an adjustable difficulty level and special rewards.  
*   Custom towers editor where you can construct your own powerful weapon.  
*   Remappable keyboard or gamepad controls. Please note that the game was not designed for mouse control.

Feature scans:
- Proton/Linux: score 25; verdict: Minor Tweaks Required; summary: The filtered reviews contain two matching reports that the game works on Steam Deck after switching compatibility settings to Proton. No Linux-specific launch failures, crashes, anti-cheat blockers, or extensive workarounds are mentioned. The only noted friction is a simple Proton compatibility selection, indicating mostly working Linux/Proton support with minor tweaks.

- Hardware Profile: No data
Feature extractions:
- Community Price:
  - Community fair range: $5.00 - $12.00
  - Reasoning: The reviews give a direct price anchor: one reviewer considers 11 EUR (about 12 USD) acceptable at full price, and others say the price point reflects the content or that the game is worth the price. However, several reviewers still recommend waiting for a sale or discount, and one mentions buying only when it drops to a buck or two. This suggests the community sees roughly 5-12 USD as a fair base-game range, with the upper end tied to the explicit 11 EUR full-price justification and the lower end reflecting the common discount-seeking sentiment.
- Playtime Metrics:
  - Game completion: 10.0h
  - Story completion: 7.0h
  - Session length: N/A
  - Endgame: 30.0h
  - Reasoning: The quote 'It took me around 10 hours to complete all missions' supports gameCompletion at 10 hours. The quotes 'From start to finish, the campaign was 7 ish hours' and 'I was able to beat the main campaign in about 5.3h' support a storyCompletion estimate around 7 hours, with the 5.3h figure as a lower bound. The quote '10 just normal campaign to 40 hours new game and the procedural levels' indicates total playtime can reach 40 hours, so endgame content beyond the 10-hour campaign is roughly 30 hours. SessionLength is null because the reviews report inconsistent session lengths without a clear typical value.
- Time-to-fun:
  - Summary: Protolife often starts opaque because the campaign has little story framing and early levels act as an unannounced tutorial, but many players report that the defensive strategy loop clicks after perseverance and mastery of construction and unlocks. Some reviewers find it addictive immediately, while at least one loses interest quickly, so the dominant onboarding profile is delayed enjoyment.
  - Stance: Clicks after
  - Anchor: The mechanics clicking after perseverance and mastery of the construction/defense systems
  - Time to anchor: N/A
  - Friction: No story framing for the campaign; Early levels function as an unannounced tutorial and throw players in; No tutorial or poor introduction; Learning curve and pacing issues; Tutorial can run long enough to pass the 2-hour return window; Endless mode is poorly introduced or not introduced at all
  - Unlock drivers: Perseverance before the game clicks; Returning to the game later and having mechanics click better; Unlocking new tools; Mastering the construction system and efficient structures; Each level introducing new turrets and enemies
  - Conditions: Familiarity with similar strategy games; Good keyboard dexterity; Enjoyment of designing complex defensive systems; Interest in experimenting with unconventional strategies; Preference for slow progression and unlocking items; Tolerance for learning curve and pacing issues

The developers' hard work and added replayability, fresh mechanics in the genre, and the control scheme and UI that uses block placement instead of menus are all valued.
