An application for memorizing words.

An application for memorizing words.
Hello. My name is Alex.
I am learning Spanish. And I need to memorize words.
The idea came to mind to make an analogue of Anka or Mnemosyne inserted into a simple game (to hide the burdens of learning behind the interest of playing)
The simplest option is a shooting range (like shooting roosters-

only with evil enemies – for example, evil robots)
Please tell me whether it is possible to do in Verg3d:
0. A test like “Who wants to become a millionaire”? Which will appear when you open the chest or pick up something?
1. the very first and most important thing –
the ability to somehow add and change words in the Test? Fast, may be the whole list?
2. A weapon sight instead of a cursor? Like in the rooster video-example?
Judging by the examples, I can do the rest … But all the suggestions will be in my favor
Thanks in advance.
