Did anyone know, how to draw a permanent score window in a mini game?

So basically I need to draw a variable into a window, what represents the score the player earned. If I do via message as a parallel process, the player is blocked. Even with an script that allows the player to walk while the window is open doesn't work. Because it stops every other parallel process. Plus it doesn't update the score window. (\s/)

May this makes it a bit more clear, if any questions, I'm here to answer your questions.

This was the script I tried out:

Tried that one too:

The second one works so far, but can't draw any variables in the message window, hope I could get any help. /)

Can anyone help me?

The following post is interesting too.

How many points will the player be getting?

Like, what are the max points? How many points per objective?

I see, that's what I missed.
Thank you for the question, so the maximum would be about 1000 points, if you are a god like player.
My best score was 650 points, so it must be okay, if it counts to 999.

But later in the game progress there would be a mini game where you can probably get 99.999, if you are good enough.

For the first mini game it's -10 for the rotten one, 10 for the good, 25 for the best quality, and 100 for good reactions. (\s/)
