Not ironic in any way. There's a world of difference here that's covered by completely different parts of copyright laws, and often software is not covered by copyright law at all.
In Poland, copyright for artwork, music, etc., is defined in the copyright code. In a nutshell, it's illegal to share other people's work with others, whether by providing original digital files, their renderings (printouts, video recordings of a digital original, audio CD from music files), broadcasting or public performance, regardless whether it's for free or for pay, unless you're sharing it with your friends or family.
Software and architectural plans are covered by related law and governed by license. You can, in theory, steal them, but you cannot legally use them unless you also purchased a license to use them.
While the act of downloading the game and keeping it on disk, disassembling and so on is not illegal, playing it is illegal.
The developer would be guilty of illegally using other people's assets for profit.

Just going back to the game itself. What a wasted opportunity.
The artwork is great, animations are good, but there's no game or story whatsoever. The "game" isn't even a game, but a completely linear slideshow with zero decisions to be made.
For starters, the premise is ridiculous. It could have worked as a bad intro to a better game, but instead, it's all the game there is.
Elsa could have been fucking Hans or Kristoff. Both would have been good for setup and dramatic effect. Fuck, she could have been with Sven or Olaf and it would make for a story (not a good one, but still).
Instead, she's fucking a disembodied dick that belongs to nobody.
