Trinity Fusion

Introduction

Trinity Fusion sends the player across three parallel realities within a collapsing multiverse, running each attempt as a separate version of the same character before fusing parallel selves, powers and worlds together to build increasingly potent runs. Developed and published by Angry Mob Games, it left Early Access and released fully on 15 December 2023 for NZ$28.99. Over two years on, it holds 898 Steam reviews sitting at Very Positive, roughly 85.3%, with recent sentiment running notably softer at 73% across its most recent 100 English reviews. This review reads a substantial share of both the negative and positive samples, and finds a game whose central concept earns real credit, wrapped around a controls complaint dominant and specific enough to define its reputation.

A genuinely original fusion concept

Start with what draws real, consistent credit across this review's sample: the core idea of fusing parallel versions of yourself and your abilities mid-run is genuinely distinctive within a roguelite landscape that often recombines familiar building blocks. Art direction and animation earn steady, specific praise, with reviewers repeatedly singling out enemy attack and death animations as a particular highlight, and character models and world design draw matching credit for visual identity. Combat, when it lands cleanly, is described by several reviewers as stylish and visually satisfying, giving the game real presentation strengths even among its harshest critics.

Controls that reviewers measure against a genre benchmark, and find wanting

Set against that praise, this review's sample shows unusually strong, specific agreement on where Trinity Fusion falls short: control responsiveness. Reviewers repeatedly and directly compare the feel to Dead Cells — the clear genre benchmark for this style of action roguelite — and find it falling short, describing animation-locked attacks that can't be cancelled and a dodge-dash several call unresponsive, particularly when trying to escape consecutive enemy attacks. This isn't a scattered complaint; it's the single most repeated specific criticism across this review's negative sample, recurring from launch through recent reviews rather than fading with patches. A more serious, concrete bug compounds the frustration: multiple reviewers report permanent traversal abilities, earned by defeating bosses, can inexplicably disappear afterward, blocking further progress entirely. A patch coinciding with the December 2023 full release addressed a related control-locking issue, which returning reviewers specifically credit — but the ability-loss bug is reported as persisting past that fix in reviews dated well into 2024 and beyond.

A metroidvania label that doesn't quite fit

A separate, smaller but recurring complaint concerns genre framing: Trinity Fusion is frequently categorised and discussed alongside metroidvanias, but reviewers who came specifically for that structure report there's no real interconnected map to explore or backtrack through with newly earned abilities — it plays, several say plainly, as a straightforward platforming roguelite rather than anything metroidvania-adjacent. That's worth flagging directly for any reader shopping by that specific tag.

Final Verdict

Trinity Fusion earns real credit for a genuinely original central idea — fusing parallel selves and abilities mid-run — rendered with strong art direction and animation work. What keeps this from a stronger recommendation is a dominant, specific controls complaint that reviewers measure directly against Dead Cells and find wanting, compounded by a real progression-blocking bug that outlasted the patch meant to address related issues. For players drawn specifically to the fusion concept who can tolerate looser, less precise combat than the genre's best offers, there's a worthwhile idea here. For anyone chasing Dead Cells-calibre responsiveness or genuine metroidvania exploration, this review's own sample suggests looking elsewhere first.
