By now they are. Right now I'm studying game design and game development and I still not reached the part of the course regarding integrations. In the future It will not be 0€... but there are some things that I need to learn about this. And I didn't expect the game to BOOM so much in itch.io, to be fair.
I expect it not to be a problem cause the game is fun enough withouth it (I expect)
But by now, yes. Consider it as a temporal cheat console, as in some old videogames (The first Civilations had the cheat system directly in the menu). Be carefull with it and don't break too much your gameplay experience
