Calling this "inspired by" Progress Knight in a footnote is wild when the entire first 30 minutes is virtually unchanged from the original.

I didn't play longer than that once I noticed strength XP buffs were broken. (maybe due to being misspelled "strenght"?)

I know the creator made the game entirely public domain (licensed under "unlicense" https://github.com/ihtasham42/progress-knight/blob/main/LICENSE)...

...but I feel like you could be a bit more honest about how much you took here? This is like taking The Great Gatsby, changing the title and only rewriting the last chapter, and then re-releasing it crediting yourself as the author. Just be honest about what it is, you'd get more eyes on it and more goodwill instead of scowls.
