MIO: Memories in Orbit

Few games in this library have a design disagreement this specific and this evenly argued. MIO: Memories in Orbit's reviews aren't split on whether it's beautiful — nearly everyone agrees it is — they're split on one deliberate mechanic, and both sides make their case with real detail.

The visuals nobody disputes

Across the entire review sample, positive and negative alike, one thing goes essentially unchallenged: this is a gorgeous game. Reviewers consistently call its hand-painted style among the best the metroidvania genre has produced, and even the most frustrated negative reviews open by praising the art before getting to their complaints. The platforming, once its full toolkit opens up, draws similar praise for responsiveness and precision.

The mechanic that splits the room

Here's the specific design choice at the center of nearly every substantive negative review: as MIO progresses, your maximum health is permanently reduced for narrative reasons — a story-driven punishment mechanic layered on top of exploration rather than a reward for it. "As the game progresses you constantly lose max health for 'plot reasons,'" one reviewer writes. "Instead of exploration being meaningful and interesting, the game deliberately punishes you for it instead." Another, more vividly, compares the experience to being served a five-course dinner only to watch the chef throw each course in the trash one by one — a review that went, in their words, "from a 9 all the way down to a 4/10 by the end." A specific zone, the Vaults, comes up independently across multiple reviews as the worst-designed section they've encountered in any metroidvania, with the permanent health loss compounding exactly when the platforming challenge peaks.

The other side of this argument is just as detailed, and it's worth taking seriously rather than treating the negative reviews as the final word. One of the most-upvoted positive reviews addresses the criticism directly: "most of the negative reviews here come down to one thing: expectations," arguing that genre comparisons to Hollow Knight have set an unfair bar the game was never trying to clear on those exact terms. Another reviewer, with 34 hours logged, pushes back specifically on the "punishing" framing: "I don't find it nearly as punishing as most reviews are stating. The boss fights have very clear tells and plenty of time to react." A third predicts the game will be remembered as "misunderstood at release" and go on to be seen as a classic — a strong claim, but one made after finishing the game 100% rather than bouncing off it early.

Reading the completion data

The achievement curve shows a real drop-off consistent with the difficulty debate. Early milestones — reaching the hub, unlocking the first dash — sit between 70% and 75%, meaning most buyers get a solid start. Completion-focused achievements, tied to collecting every shield and module, fall to around 10-13%, a meaningfully steeper drop than many metroidvanias in this library, which fits the pattern of a game whose back half loses a real share of its audience to the exact mechanic its critics describe.

7.5 out of 10. MIO: Memories in Orbit earns real praise for its distinctive art and precise platforming, and it deserves credit for taking a genuine design risk with its health-loss mechanic rather than playing it safe. It's held below the top tier because that risk clearly didn't land for a substantial, detailed, and articulate share of its players — not a vague dissatisfaction, but a specific complaint about exploration being punished rather than rewarded, concentrated in one widely-flagged zone. Whether that's a bold narrative choice or a genuine design misstep is something this review's own sources can't fully settle, and it's worth forming your own opinion on rather than taking either side's word for it.
