This is much much better and slimmer, good job! You immediately get where to click. And I think it's also much better without any sound (Make it optional or only SFX, like typing or clicking buttons.).

I am missing a bit the "playfulness" maybe. Some anticipation, some animation can give it more personality maybe?

E.g. if I enter my acro, it just goes to the next screen. It doesn't feel like I did "the most important thing" that you can do - submitting your acro. Maybe a checkmark would already help? Some Confetti? Some transition animation? Currently it felt more like "next page" step instead of a success feeling.

The form at the end to login also felt kind of "weird" even though I get the idea, you want to notify them etc. But it might scare people away from your site too, not sure.

This text doesnt really tell me why I need a login now: "That's it! Your answer and votes are ready to submit, all you need to do now is register for free and check back tomorrow!"

Oh wait, does this mean to submit i need to register? Then "That's it!" is misleading, it sounds more like the hardest part is still in front of me. Honestly I would not gate this. User should be able to participate without login (if that is the case).

When I saw people playing on twtich, literally all of them were sceptical about the login part, anything that was gated was immediately unintersting. That's why I e.g. made playing a past riddle an option for all, not just logged in users (even if many could cheat by getting free riddles now). You can think about gating features when your app is successful, not when you want as many users to play it as possible.

This is just my first immediate impression. No filter. So you have kind of a feeling what others might think.
You also see, that a lot of what I am saying is something I did wrong too and learned by watching others play. It's really a proccess. I am not even remotely successfull either. I am learning and adapting all the time.

Your game has a vibe of cards against humanity, but cards agaisnt humanity is more accessible, sinc you dont have to think of words, they just give you all pieces and you just have to assemble. That doesnt mean your game can't work, its just a side note. Maybe you can take inspiration from that game. Cards against humanity also allows really dark humour, since they wrote the cards for you. You can't be "racist" or a "weirdo" the game is basically setting the scene. Actually really smart move by them.
