Oh wow, now there's a KonoSuba parody in the making eh? What a wonderful surprise, hopefully because of the contest setting the developer is gonna add Wiz, Chris and Yunyun among others.
If you can I suggest go for it, it's never a bad idea to make more parody games as long as you have the skills and art to do so, it would be a nice change of pace to introduce a new variety that isn't the umpteenth Naruto or Harry Potter clone in my opinion, in the meantime let us enjoy this little piece of work and hope that it may turn into something greatI planned on making a KonoSuba game myself awhile ago, but seems like somebody beat me to it.
