Really cool to see PICO-8 submission! Hat's of that you managed to do this in 3 hours!
How did you do this "diagonal" sprites in PICO-8? I mean that they are not aligned by axis. Did you make more sprites for each angle?
As you also mentioned in comments that it depends on the wind... I think that when it was blowing full force in one way I couldn't do almost nothing.
Thanks! So the tower is actually made by drawing a bunch of lines closely packed together. And it uses the tline function to sample a portion of the map that contains the brick texture. The relevant part of the code is here

Yes, the wind does get pretty strong. It's meant to slowly increase in strength so it gets more challenging as time goes on, but it's very random so it can get strong pretty early.
