How to Fish Engine and Graphics: Unity and Lowpoly
Contents
The engine behind a game is usually something you have to infer from indirect clues. Not here: the developer answered it in one word in his own devlog, long before the game became popular.
Unity, stated plainly
The studio’s public Bluesky devlog opens on 15 August 2025 with a line about starting work on a fishing game. The next day, answering a reader asking about the engine, the author replied briefly: no, it is Unity.
That means the gap between the first post and the 20 August 2026 release is one year and five days. That is the full development cycle — not a journalist’s estimate, but the studio’s own dates.
Lowpoly is a decision, not a saving
The same post from 16 August 2025 contains the most honest line in the entire devlog: the author wrote that they are two programmers with limited skill when it comes to art, and that the game would probably be lowpoly with some shaders for a more unique look.
It is rare to see an art style explained this directly, with no marketing talk about an authorial vision. Two programmers cannot produce photorealistic graphics — and instead of doing it badly, they picked a direction where a small budget does not show.
The early devlog posts back this up literally: the first versions were shown with deliberately crude placeholder assets, and the author never hid it.
What that produced in practice
| Parameter | Value | What it means |
|---|---|---|
| Disk space | 1 GB | smaller than a single modern texture pack |
| Minimum GPU | GTX 1050 / RX 460 | a mid-2010s budget PC |
| RAM | 8 GB | standard laptop spec |
| Recommended requirements | left empty | the studio simply did not fill them in |
One gigabyte on disk says a lot about the approach on its own. Most modern games in this genre weigh tens of gigabytes precisely because of the high-resolution textures that are absent here by design.
The price of being light
Light graphics do not mean performance was flawless. Patch 1.0.5 lowered the minimum locked framerate from 50 to 30 — meaning weak machines were hitting that floor and it had to come down.
The same patch fixed a bug that only appeared at 4K: skins disappeared inside the slot machines. That is a classic lowpoly-project situation where the interface is not tested at every resolution.
How the visuals grew
The devlog dates show what was added to the world across the year: sharks in late August 2025, a seahorse in September, the casino at the end of September, grilling a few days after that, melee combat in October, seagulls in late October, a knife in November. The studio showed a new gameplay trailer on 27 November 2025 — nine months before release.
Frequently asked questions
What engine is How to Fish built on?
Unity. The developer answered that question directly in the Bluesky devlog at the very start of the project.
Why does the game look so simple?
It is a deliberate choice. In the devlog the author wrote that they are two programmers with limited art skills, so the game would be lowpoly with shaders for a more unique look.
How much disk space does it need?
1 GB according to the Steam minimum requirements, a direct consequence of that same lowpoly approach.
Will it run on a weak PC?
The minimum is a GeForce GTX 1050 or Radeon RX 460 and 8 GB of RAM. That is a mid-2010s budget PC.
