Ren'Py 8.4.1 web build
Realm Invader
Realm Invader runs on this page at Episode 2 Part 1, in a build the developer labels 4K. Elsewhere in this catalogue a game announces itself as Standard 720p and weighs 97 MB. This one says 4K and weighs 68. Those two facts sitting side by side tell you something useful about resolution labels.

A resolution label is not a size prediction
The instinct is to read 4K as heavy and 720p as light. Across two real builds in this catalogue, the 4K one is thirty megabytes smaller.
Resolution sets the ceiling on a single image. Total size is that multiplied by how many images exist, then divided by how hard they were compressed. A short episode at high resolution can easily weigh less than several seasons at a modest one.
So the label tells you how sharp a scene can look, not how much game you are getting. Those are separate questions and only one of them is answered on the tin.
What you are actually loading
A measured 68 MB across the four files. Take off the 33 MB of shared engine and the game's own content is around 35 MB.
For an episode and a part, at 4K assets, that is efficient. It also confirms the reading above: this is a focused instalment rendered well rather than a sprawling one rendered cheaply.
Nothing downloads until you press the button.
Episode 2, Part 1
Two levels of subdivision means content arrives in small, frequent pieces rather than large occasional ones.
The practical consequence is the one that always follows from frequent releases: you cross more version boundaries, and each one is a small chance an old save confuses a new build.
Twenty one tags puts it on the broader side, which for an episodic project usually means the routes were planned out before the episodes started shipping.
Why we print the whole build label
Most sites tidy these strings away and show you a clean name. We print what the developer actually wrote, because the tidying is where the information gets lost.
Episode 2 Part 1 4K tells you the release model, your position in it, and the asset quality, in four words. A tidy Realm Invader tells you nothing.
It also keeps us honest. If we serve an older build than the one you saw elsewhere, the label says so rather than hiding behind a version free title.
Realm Invader, answered
Does 4K mean it is huge?
No. It weighs a measured 68 MB, less than a 720p build elsewhere on this site. Resolution caps how sharp one image can be. Total size depends on how many images exist.
How much of that is the game?
Around 35 MB. The other 33 MB is the shared engine that every build of this kind carries.
Where does Episode 2 Part 1 sit?
It is the first part of the second episode, so content arrives in small frequent pieces. Export a save between releases.
Does it work on a phone?
Yes. The build declares Ren'Py 8.4.1, so touch and audio behave properly.
