You know you could download the game as it is, on itch.Io for free. To open your eyes and start reading isn't that hard to do.
It even says so in the first line. This game is free. Because the main reason it was put on Itch.IO was to get some feedback for the early version. But keep in mind even it is for free right now this might change, and also nobody can life from rainbows and sunshine. To support developers that make games you enjoy is the least you can do. And if not mony wise than be active on the forum, help find bugs, tell them your opinion on changes and stuff.
