The Web version cant be played in browser if its hosted on a server. I am running a local server for my kids to have a more safer, curated internet that we can use. I cant seem to use it this way, as the game is calling me a thief xD
EDIT: oh now I noticed that the web version remained as a downloadable by accident.
Yea, it is a game that as a web version checks if it's being run on itch or gd.games.
You can download the Windows, Linux, Mac versions though that are not requiring that.
This measure was for preventing other parties on nabbing the game and running them on their platforms that give them revenue etc.
