Heros and Monsters: Idle Incremental

Introduction

Heros and Monsters: Idle Incremental sends a party of adventurers against the dark sorcerer Mordek and his escalating horde, with combat, stat growth and gear entirely automated once you've spent your currency on upgrades. Developed solo by Mathew Perry and released 21 July 2023, it markets itself explicitly as an "ethically free" idle game — no ads, no microtransactions, nothing to buy — and sits at a lifetime Mixed 69.4% across a modest 121 reviews. This review reads the full English-language negative sample and a substantial share of the positive one, and finds a game whose two defining traits sit in real tension: an unusually principled monetisation stance that earns sincere, repeated praise, wrapped around a core loop several of that same audience describes as too thin to sustain much play.

A monetisation model worth taking seriously

Set against how this library usually has to write about free-to-play idle games, Heros and Monsters is a genuine outlier, and it's worth stating plainly rather than passing over quickly. There is no premium currency, no advertisement anywhere in the client, and no purchase of any kind available — this review confirmed that against the current store listing rather than taking the game's own marketing at face value. Reviewers independently echo it as the standout feature: one of the most-upvoted positive reviews opens by calling it "super cool that the game is 100% F2P no hidden cost, NOTHING to buy," adding that it's the first game of its kind they'd seen on Steam. Multiple others use nearly identical language — "ethical free to play," "no hidden cost." For a library that spends considerable time cataloguing energy timers, pay-gated offline progress and pressure mechanics in this exact genre, a solo developer shipping a completely clean model deserves credit on its own terms.

The game underneath is thin

The difficulty is that a meaningful share of this review's sample, on both sides of the recommend button, describes the actual game as underbuilt. There are no maps or areas to explore — you fight the same boss repeatedly as it scales in strength, and progression amounts to a handful of stat upgrades and gear generation rather than distinct systems to master. One reviewer sums up the mechanical depth bluntly: "no real systems or anything to do here besides 4 basic stat upgrades and generating gear that also is those stats." Several positive reviews concede the same point in softer language, calling it "very bare bones" while still enjoying the free, low-pressure loop for what it is. The prestige system draws specific criticism for not meaningfully changing how the game plays after a reset — one reviewer describes finding "nothing you get" from it beyond incremental number growth, and Steam's own achievement data shows a sharp fall-off once character-specific late-game milestones are involved, with several level-20 character achievements sitting around 7% against 80–90% for the earliest kill-count achievements.

Technical issues compound the thinness for some players. One 2025 reviewer, with over 1,300 hours logged, reports Steam achievements failing to register at all and a "sky forge" mechanic that stops working correctly after a single prestige cycle, with crafted items and progress lost on subsequent resets. That's a specific, credible complaint from an invested player rather than a drive-by account, and worth weighing against the otherwise positive impression the free-to-play framing creates.

A developer players genuinely vouch for

What tempers the thin-content criticism is a consistent secondary finding: reviewers across the sample describe the developer as personally active and responsive, several by name-checking a community Discord where feature requests get implemented. The patch history backs that up — an "Automate everything!" update in June 2024 specifically added the ability to automate the ascension process, addressing a complaint from around the same period about spending "2 hours" manually clicking through upgrade points after a big prestige. The game passed 10,000 unique players by April 2025, per the developer's own announcement, which is a meaningful audience for a completely free solo project. Update output has gone quiet since then, though — this review found no patches in the sixteen months before writing, despite English reviews continuing to land as recently as July 2026, suggesting a small but still-present playerbase working through a game that has, for now, stopped growing.

Final Verdict

Heros and Monsters: Idle Incremental earns real credit for a monetisation model this library rarely gets to praise without qualification — genuinely free, genuinely ad-free, built by a developer its own community describes as trustworthy and responsive. What keeps the score modest is that the game itself, underneath that model, is thin: no map, minimal enemy variety, a prestige loop several reviewers on both sides call barebones, and at least one credible report of broken progression systems for invested players. It's an easy recommendation for anyone curious about a genuinely no-strings idle game willing to spend an evening with something small, and a harder one for anyone expecting the content depth this genre's better-resourced entries deliver.

Players who want that same low-pressure idle loop but expect deeper systems and content to grow into over time may find Wanderer's own progression a more substantial next step.
