I am sorry that this prototype shows only the aspect of an asset bought on the Unity Store. As my other prototypes I am using already-made assets to create few minutes of gameplay, based for example on the last game I played, or a short part of a movie etc. not for money but because I like video games.
I also would remind to the developers of Itchio (because I am noticing that these critics are coming mainly from developers) that "game design" is part of game development (not just who creates "content" (artist) and "scripting" (programmer)), and elements as game progression, pacing and general atmosphere are important parts of a game that needs lots of iteration.
