5 gb RAM usage is INSANE for a game like this. I don't want to point fingers but the only time I've seen something like this was when I encountered viruses.

Now that the update is out, Yumi actually does consume way less resources than she used to, roughly 700 mb, which is actually less than many other desktop idlers.

Kinda makes me wonder what was the problem to begin with?

Now all I need is a button to make her able to be clicked through.

Edit because I'll say what I think and no one can stop me: I think this game would be infinitely better if it didn't have sexual content, like, I don't even understand why that's a thing..? Isn't a cute girl at the side of your screen typing away in sync with you enough? Let the lewd modding be done by the community or at least give me an option to disable NSFW.

Every click with your mouse or keyboard you do will give you a point, and sometimes a random item can come out from a bonus point system with a 30 min timer. In my case, i got glasses, that were locked for a specific pose that i couldn't afford.

And other than her just sitting there, and saying the same two lines over and over again, you can click on her, making her say 2 more lines and that's it.
You can undress her if you wish, you can make her stop talking (highly recommending) and you can even set a timer if you ever would want one. (Not possible to change her position at the start without buying new poses)

Auto-clickers does not work, I tried to see if it was possible. No cheesing for points available.

As for the location, size, and any other useful function as a desktop companion, i haven't found anything useful other than her trying to act erotic and making weird cat noise every 5 seconds and causing a distraction. She can either get big enough to cover your screen, or get small enough to fit your top corner and be out of the way.

For you who wanted this desktop companion for the NSFW option, i think it is possible to do so, but you need to unlock them first. And the grind for the points will make you wait for quite some time
Also, even if they are cheap, there are some cash items that you need to pay for with IRL currency, real cheap, but they still gonna ask you to pay up for those kind of toys.

I found this cat girl too distracting for me to have active while i work, and there are not much you can do but hope to get lucky to get an item or two every 30 minutes when the timer will give you a small point boost.

Customization's are as good as non-existent, any items you can get are either behind an RNG-system or a paywall, and she keeps on making noises to distract you while you are doing other things on your computer.
There are better desktop companions out there, this one was not for me.

writing the timer json on disk every other second surely is a good idea, just as adding not working microtransactions.
