Can make 4, 6, 7, 8 letters ones? 5 letters in dictionary seems too little words.
Yeah, there are 800 some in the word list and a few thousand more in the obscure list, so this is a bit less than half the ideal sizeā¦ but itās not an order of magnitude off.
Given the vowel problem you brought up before, four letters would be way too little (you couldnāt eliminate consonants fast enough) and I think 7/8 letter words is approaching the limit of numerical perception (you shouldnāt have to count letters), so that just leaves 6 as a reasonable possibility.
Testing it out locally, yeah six would work. There are about twice as many 6 letter words, so that would be about the right size dictionary. And it kinda makes up for the fact that almost all words end in āaā anyway 
I guess my only concern is that itās a little harder to think up six letter words than five (at least for me). What do other people think? 
Iām happy to switch it to six letters if other people prefer it that way 
Iām ambivalent myself. Itās surprisingly a pretty easy code change to make.
Donāt switch, make a new one! Duplicate! Itās not needed to think of words, just have some words ready, eliminate some consonants, start to type the words in dictionary for more words based on the clues. vacana, vedana,
Go for it! Fork the code, change this constant to 6 and run cd makedicts && node makedicts.js to generate the new dictionary 
So download the thing first? Or copy paste to which software? What is run cd thing? command mode? What language is this written on? How to host this on a blog?

Hmm I havenāt done node on Windows before. You can either install WSL+nvm or give nvm-windows a try. Then use nvm to install the latest node version.
