the improvements were great! love the thunder sounds! and the flow of the music!
Some things I think you could look into:
- the music doesn't loop;
- is it possible to open the menu while the upgrade messages appear, when I did that when taking the first missile tank, the game froze;
- when entering a door you have to press the move button again, which can lock the momentum of the game, I don't know if I could explain it well;
- one thing that would be nice is a button that locks your position, allowing you to aim freely, so you don't have to walk to shoot diagonally;
But again, it's a great improvement.
