When using the itch.io launcher, it downloads the game I assume but not the executable. At least not for linux. The only options for what to launch from the launcher are "nw", "nacl_helper" and "nacl_helper_bootstrap". None of which launch the game. I tried to download the files from the site but it always prompts to pay, which is fine however I was under the impression this game was F2P as none of the download buttons have a price tag and that I was able to download the game from the launcher. Is the only free way to play this game in a browser or am I missing something?
