Synopsis
A city-building SLG where you plant “Mira Flowers” that generate air and construct an underwater metropolis. As air accumulates in the flowers, tap the speech bubbles to collect it—air is a crucial resource consumed by most actions.
Note: There is no tutorial, so please check the in-game guide. The flowers can only be planted on land level 2+, which levels up randomly through resident actions, so you can’t freely place air flowers wherever you want. However, buildings can be relocated at no cost, allowing adjustments later. The relocation system works by fixing your selected building and moving the entire map to choose placement, which may feel unintuitive at first.
The game features charming pixel art animations, appealing character designs, and an engaging story centered around the protagonist Hele. Three difficulty levels ensure newcomers won’t get stuck. If the sample visuals appeal to you, this is highly recommended.
**Editor’s Review**: “Hele’s Underwater City Plan” is a fantasy-themed SLG centered on an underwater setting with a charming female protagonist. The pixel art creates an inviting atmosphere with excellent immersion. The sandbox simulation mechanics make gradually developing the underwater city enjoyable, with well-balanced progression depth. While initial controls may feel complex for first-time players, mastering them reveals a satisfying blend of nostalgic pixel aesthetics and mature storytelling that keeps you coming back. Reasonably priced and accessible to both casual and hardcore players alike.
Editorial Review
Hele’s Underwater City Plan occupies an interesting niche within the SLG sandbox space: a resource-management game where atmosphere itself becomes both the building block and bottleneck. Unlike typical city builders that grant you terrain freely, this work makes air generation the central tension—you’re farming magical flowers to literally breathe life into your underwater metropolis. It’s a clever thematic marriage of mechanics and setting that gives the core loop genuine purpose beyond mere optimization.
What distinguishes this from standard settlement sims is the stubborn refusal of convenience. The land-leveling system ties expansion to resident behavior rather than player will, forcing adaptation rather than pure strategic vision. The relocation system, while genuinely awkward at first, becomes an unconventional puzzle where you’re repositioning the entire map rather than dragging individual buildings. Combined with the total absence of a tutorial and a three-tier difficulty spread, this is clearly a work designed for players who find friction stimulating rather than frustrating. The pixel art and character animation pull considerable weight in softening the systems’ rough edges, and the presence of an engaging narrative anchored to protagonist Hele suggests the developer prioritized world-building alongside mechanical depth.
This appeals most acutely to players comfortable with experimental resource management who value pixel art aesthetics and don’t mind learning through trial, failure, and the in-game guide. If you’ve bounced off punishing sandbox sims or demand hand-holding during onboarding, the difficulty curve and opaque mechanics will exhaust you quickly. But for those genuinely attracted to the visual samples and willing to treat the early hours as slow discovery rather than tutorial, Hele’s Underwater City Plan delivers a distinctive take on city building with real atmospheric (and thematic) weight.
