Hello Caruise!
Welcome here. Feel free to ask any question.
You are now facing a panel made of red 10 buttons arranged like this:
1 2 3
4 5 6
7 8 9
10
The goal: turn them all green to open the spaceship door
Note that the door of the spaceship will open for approximately 1.5 second so make sure you are ready to RUN inside the spaceship when all the buttons will be green
At first, the 10 buttons are red. If you touch any of them, the one you press & the next 2 in sequence are changing colour: the red becomes green, the green becomes red. The goal here is to get them to turn all on the green colour.
Here's the dummiest solution I can come up with, and I don't even feel ashame of myself using it since I'm not a puzzle lover

Solution:

You start initially with 10 red buttons.
If you touch them in sequence, the 1st, the 2nd, the 3rd, ..., the 9th, & the 10th,
you'll make them turn all once from red to green, then all once from green to red, & finally all them from red to green
You'll eventually end up with 10 green buttons. Hurry up inside the ship!!!
There are more "brilliant" solutions out there... I stick to dummy ones when I can
