Hey I can't really play this game because the tutorial text doesn't seem to scale to fit my screen, and I can't figure out how to play the game otherwise. Seems like an interesting idea though, and having this be your first Godot project is cool!
Oh uh, the tutorial was added in last minute so I forgot to make it HUD and whatnot. Just use arrow keys to stretch, WASD keys to shrink, hold in the direction to stretch/shrink that way
