On the bright side though, I'm hoping that the mere existence of rocketcrab may inspire more developers to build even more diverse mobile web party games. Without rocketcrab, not only do you have to design and develop a game, it will be all for nothing if you can't find players to play your game, which is tough! The idea is that adding your game to rocketcrab will help it find an audience! if that makes sense :)
Also I have a giant list of mobile web party games that I want to try to add but haven't had the time. If anyone wants to give it a shot, rocketcrab PRs are open ;D

You only note negative things, not positive things. This colors the whole post.
You use italics and "Oh,", which makes it more conversational, and it sounds exasperated to me.
Your questions at the end could be construed as rhetorical, rather than constructive, partly because you suppose an answer.
Suggesting that the games that are there exist because they are "easy to program" could be seen as a negative comment on the creator's programming ability or drive.
As the poster of this link and someone who enjoys the games a lot, I think your criticism about lack of variety is valid (if out of place for a collection of free games) and your phrasing wasn't aggressive or anything, but the above are some points that I watch out for in my own writing, particularly the first one - even if I don't like something, I find it useful to point out positive aspects to make it clear I'm trying to be constructive.
Oh, and drawing games.
Anything else? I guess the secret-info ones are easy to code?
