Thank you for your feedback!
I agree the artist did a great job for the game, both what you see in the game itself and visualizing concepts and ideas for implementation
I'll see about adding more sound effects and ambience soon, I would also want to change the shooting sound to something more snappy and satisfying, right now it's just a heavily edited "P" that I recorded
I'm really glad you found the game fun to play! And I love the idea about events occasionally happening to spice up the gameplay, I might explore the idea in my spare time at some point. Though right now we don't have any plans to develop any big updates for the project, we'll see what the future holds!
