I think what they meant was the “Tasks” page with all the “subscribe to our socials,” “join our Discord,” and “oh, and play some random game on another website” stuff - at least that’s what I assume they mean.
While I fully agree it’s pretty clear there’s no monetization anywhere in the game and that it’s very obviously free, even to kids, I also feel like this reward system leaves a bad taste in an otherwise really fun and unique game. While it’s completely up to you to decide what to include, I honestly think the game is better off without it. I noticed it immediately too, and it instantly reminded me of those crappy phone games where you get a boost after watching an ad.
Anyhow, this is just my opinion. That said, I really liked the game and I’ve already wishlisted it :)
