    Example report

    Escape Your Doom

    Design readout from 3 reference games and a pre-production pitch.

    Idea viability

    Promising

    The core hook is clear and differentiated enough to justify a prototype, but its value depends on proving that style-driven survival creates meaningful decisions rather than a cosmetic score layer.

    • The health-is-style rule gives the combat loop a sharp, explainable identity.
    • The horde framing is familiar, so the game needs strong proof that precision changes survival outcomes.

    Indicators

    Moat2/3

    The style-health coupling is promising, but the rules need a sharper signature.

    Differentiation2/3

    The hook reads quickly, though the genre wrapper is recognizable.

    Market fit2/3

    Score-chasing action has a legible audience if mastery feels fair.

    Concept depth2/3

    The loop has room to deepen through authored missions and build decisions.

    Positioning verdict

    Position this as a focused premium action score-chaser: sell the style-health hook and authored survival missions, not a broad horde fantasy. The concept reads strongest when it is compact, polished, and replay-first, because the references show mastery action wins when every move matters and fails when content breadth or onboarding overreach muddies the core loop.

    Kill criteria

    • If players cannot clearly explain how style converts into survival after a short guided session, the core hook is not landing.
    • If optimal play trends toward safe circling and attrition instead of expressive aggression, rethink the combat economy.
    • If testers frequently take damage they describe as off-screen, unreadable, or visually buried, do not advance content production.
    • If score play is dominated by one repetitive route or exploit, the replay loop is too shallow for the product lane.
    • If repeated mission attempts do not produce observable learning and performance improvement, the authored mastery premise is failing.

    Open questions

    • What specific actions raise style, and what specific events break or drain it?
    • Is healing direct, shield-like, threshold-based, or tied to temporary overheal from style performance?
    • How many player weapons or stances are planned, and how distinct are their scoring roles?
    • Are missions purely fixed waves, or do they include boss encounters or elite climax rounds?
    • What forms of progression exist outside player skill and leaderboard improvement?
    • How many arenas and enemy archetypes are actually in scope for launch?
    • Is there any assist mode, training room, or onboarding layer for players below the expert target?
    • Are leaderboards global only, or split by loadout, difficulty, and modifiers?

    Analyze your reference games before you build.

    A 97% positive rating doesn't mean every system is good. Blitz shows you where a game shines and where it stumbles — what to borrow and what to leave behind.

    "At Ascension 10, the game becomes bad; I often can't get the cards I want, take huge damage, die many times in a row before winning once"

    "It becomes repetitive after a few hours when you want to grind Ascension"

    "Grinding up to Ascension 20 didn't really appeal to me, so I lost motivation to keep going"

    Blitz shows you exactly what to borrow — and what to leave behind

    You're making a roguelike deckbuilder. You reference Slay the Spire and add a 20-level ascension system because that's what the hit game did.

    Don't copy the complaint

    A 97% positive rating doesn't mean every system is 97% good. Blitz surfaces what players actually love — and what they tolerate — before you build the wrong thing.

    Test your idea against real player evidence, not surface-level review scores.

    Built on top of Mappex pipeline

    Blitz doesn't guess. Every verdict traces back to real player reviews — processed, classified, and counted by Mappex infrastructure before the model writes a single sentence.

    880K+reviews processed
    270+games fully analyzed
    44K+design insights generated

    We're processing new games 24/7. If your reference games aren't in our database yet — no worries, Blitz will run the analysis on demand.

    Frequently asked

    What is Blitz for?

    Blitz helps you understand what your reference games imply for your own project before those decisions become production debt.

    Why not just use ChatGPT?

    Because a general-purpose chat model can make this kind of research sound convincing without grounding it in enough evidence.

    A single prompt usually reads only a thin slice of store pages, articles, or reviews and then extrapolates from that sample. Models are also unreliable at counting disputed signals, and their context windows are too small to ingest a statistically meaningful amount of player feedback for each reference game.

    Blitz runs on Mappex pipelines instead. For each reference game, it processes large volumes of player feedback, extracts and counts signals outside the model, and only then uses AI to synthesize the report.

    ChatGPT answers can look similar and convincing, but without real counting they are still guesses, and any mistake at that level pushes the final conclusions off course. Mappex does not have that problem.

    Why is it useful before production?

    Because it shows the hidden baggage that comes with your references, so you can catch fake depth, readability debt, and progression traps early.

    Can I test it before purchase?

    No. But you can check demo report to see what the result looks like and assess the quality.

    What is the refund policy?

    There are no refunds. However, if there is any bug or other issue with the report, contact mappex.ai@gmail.com with the report link and we will fix it for free.
