I opened the itch.io desktop app for the first time in a while, dead set on searching for some new games to play. I open the "browse" tab, click the tags "windows" since I'll be playing on my laptop, "free" since I'm short on money, and decide on "management" games for my search. I then decide to add "cute" to the tags to see if anything will pop up, and then I get the error: 429 Too Many Requests. So I assume a lot of people are using it. No problem. I'll wait a bit and come back later. I do so, but when I come back, I do the same thing, this time still with the same tags. I get the same error. I go back a page and see that it doesn't do it on only the first 3 tags. Then I click "newest" and I get the error again. So I do two tags and the newest and it's fine. This confirms it's a tag issue and not a too many users issue. Which isn't fantastic, since I can't get very much out of the tag system at all if I can't specify the system and cost without using up the space.
So what I propose is that the "newest/popular" tag not be included in the 3 tag limit, should that limit be important to the itch.io team. That way, the actual sorting of the games in view are not affected by that system, and you can still use three tags outside of that. Otherwise it's more of a 2 tag system, which sucks.
