More context (from dev on Reddit):

I will soon finish my university studies in Game Design and Development. I developed a tiny video game for my final project, and I’m considering uploading it to Steam.

For context: The game is a city-builder-style game about green energy and sustainability. It is somewhat educational (remember, this is a project made for the university). The game consists of building green energy generators, like windmills or solar panels, to provide energy to cities and villages. The game intends to inform about the various types of green energy recognized by the EU Commission and the infrastructure needed for them.

I believe the game has no business in the hostile Steam market. Additionally, it would be completely free, with no monetization whatsoever. The game will also be uploaded to Google Play for free, so why bother crushing 100 $ to publish on Steam instead of itch.io or any other page?

I want to learn the publishing process on Steam. I want to implement Steam API into a project (Achievements, for example). For personal satisfaction (probably the most important thing). It makes me happy to have something on Steam.
