I got to test this game for review! I have a few inputs to give, though I am not a professional game reviewer or maker or anything so take everything I say with a grain of salt ^^'
The jumping is a little weird at times anti intuitive at times, especially in areas where you jump into a new room from below. Speaking of jumping- I can't seem to use WASD to move through the game menus, so I had to switch to arrows now and then. I also find using the space bar for attacking quite confusing though that's moreso a personal preference ;v;
Now plot wise... I love biblical inspired stories, though I can't say I see a lot of aspects of the original Tower of Babel tale other than the existence of other languages and the presence of the tower itself. If anything it reminds me more of the website "Library of Babel", which I am not quite sure if it's intentional or not but I figured it's worth mentioning :0
I also think revealing the plot twist midway through the story is a little harmful to the horror aspect your game was going for, as it is usually scarier to not understand what is going on at all. Not to mention the name Babel.EXE is a little cheeky when it comes to horror stuff -w-'
All in all though I found it relatively fun to play, so I think you're in a good track!! Keep it up >:]
