Well... the web version of the game is highly compressed because of certain limits for itch io uploading. And it is outdated currently. I want to recommend you to download at least compressed build or the android build for a full experience.
If you can download the original version, then that's even better. I recommended compressed because usually that's a quicker download. Why the web build is compressed? Itch io doesn't allow big file sizes(more than 2 GB) in the game, so the game needs to be compressed to the brim.
