This has a very simple mechanic, but very bland in my opinion. Try adding a background art or something. It doesn't have to be perfect since this is I Can't Draw Gamejam.
When it's game over, the game is still going. Try adding a function that will stop the music and words falling when it's game over.
I like the music, but like I said before, it is very bland and adding some graphics to it would definitely make this better.
Overall, good job and I give it 2/5 like Byzantine did.
