It's a cool arcade game, I like the satisfaction of typing fast with the sound feed back, it feel great :)
On some points I noted, since you're using Godot, you should put stretch mode to "canvas_item" so the game will resize correctly when you put it in full screen mode.
Also the game is cool but felt too easy, or the difficulty don't grow fast enough, I ended up leaving myself, the music even had the time to end ahah (you should set it to loop)
Anyway this is still a nice fun entry
