Very nice, I like that there's sounds and visuals and it feels nicely polished and complete. The only thing i didn't like is that projectiles seem to despawn before hitting enemies a lot of the time, not sure if that's intended.
Hopefully the rainforests (and all the other life on earth, eh?) won't all be cleared for parking lots just yet. Well done, learning game dev is hard at the start, you honestly got the hard part out of the way :p
