Shooting SFX is a really good idea! I honestly completely didn't think of that. Thank you!
And yeah I agree I need a much more descriptive How To Play or possibly a tutorial of some kind.
As for shooting the animals/bugs, I definitely think I should have elaborated in the "How to Play" that you can't actually shoot them until you purchase an upgrade from the Upgrade Shop.
Thank you so much for the feedback, I really appreciate it :)
