Well done! I personally only used the spray attack as it was by far strong enough for the first 1000 points to never get into trouble - sorry, didn’t find out, what explosion does :-)
the sound effects are a bit too loud, they disable the (very good) music almost completely, so after a minute or so i had to mute my PC because it was… too much.
As I know your age from our conversation, let me double the congratulations - you’re on a good way! Keep it up!
