Great job Dav! I got over 100 that time. Also, I might add _MOUSEHIDE to some of my games, it might be useful, thanks!

And now, for the Ball Blaster -- it's a rotating ball that moves slowly across the screen, spins languidly in a 360 degree circle, and which fires shots out one side of it. Anything it hits, be that other balls or the player, loses health and eventually explodes. Player gets no points for balls destroyed by The Ball Blaster.
Or, as I like to call it -- "Pete's Mother-in-Law".

Thanks, @SierraKen! Glad you like it!
Steve, I know you were joking, but it's a good idea! Working on the big blaster ball now. Maybe it will be the big boss at the end to destroy. That's a better name for the game - Ball Blaster

I was joking about Pete's Mother-in-Law.. She's not THAT nice, after having to put up with the way Pete's treated her precious daughter after all these years!
But, I did think the idea might be something you'd enjoy incorporating into the game, which is why I mentioned it for you.
Can I suggest perhaps one really powerful boss after a couple of levels of the first one? It can be two round balls, with an oval launcher between them, that waves back and forth and shoots little green peas across the screen that stick and slow down anything they touch. You can call it "The Pea Shooter!" It'd make an awful mess of everything!
Special way to attack it would be with an unique missile which -- if it hits the top of the oval properly -- "unrolls" and covers the whole thing that works as a sort of ... latex shield... to block its steady stream of peas so the player can then attack the balls directly and destroy them!
(I know. I know. It's almost potty humor, but that still doesn't make it any less funny.
I guess I've just been feeling a little crappy lately.  )

I'll have you know my mother-in-law is a peach. It's my brother-in-law I have a problem with. He's a real son of a peach!
If I had the time, I would code this...
1) Copy image of Steve from forum.
2) Float image of Steve amongst the balls.
3) Have Steve play, and we all win when Steve shoots himself in the balls.
Now that's just good gaming!
Pete

Thanks, @Petr!
Added 2 things in v7 which make the game more attractive and fun. A big pulsating background that pulsates faster and faster as your health decreases. Looks kind of iintense. Also added Steve's Big ball that shoots out at every angle and can't be killed. It's fire bombs only hurt you for now. It flies through once in a blue moon (when (RND * 2000) = 1). Fixed some errors I found. Added a screenshot here for the curious.

'=============
'A bare-bones small shooter game that you can expand on.
'Follow game here: https://qb64phoenix.com/forum/showthread.php?tid=2978
'Coded by Dav, SEP/2024 for QB64PE v3.13
' WARNING: THIS GAME HAS FLASHING SCREENS (not much though)
'New for v7:
' - Added itense pulsating backdrop
' (pulses faster when health gets lower)
' - halfway added super bigball & bigshots
' (shots hurt you, you can't kill bigball)
' - fixed: reset all settings at start of game
'Move player using arrow keys - SPACE bar shoots.
'Shoot the balls. Don't let any hit you or pass you by.
'Moving shields appears now and then to protect balls.
'See how many balls you can shoot down before dying.
'Catch green pill to increase your health points +1.
'Catch yellow pill to be invincible for 15 seconds.
'Catch red pill to get a flash bomb! ENTER to use it.
'This is a basic shooter game that is easy enough to
'learn from and expand on so you can make your own game,
'I used balls as an enemy because I had a ball SUB handy,
'and it had a colorful effect. Used it for shots and
'for the moving shield. I also used an alpha screen
'clearing method using LINE instead of CLS. This gave
'all the moving pieces a neat trailing/fade effect.
'If you miss a ball, or a ball hits you, then you loose
'a health point. If you loose all 7 health points then
'the game is over.
'If you catch green pills, it adds +1 to your health.
'If you catch yellow pills, you are invincible 15 secs.
'If you catch a red pill it gives you a flash bomb.
'Press ENTER to use you flash bombs, which will destroy
'all balls and dropping bombs on the screen.
'There are many ways to exand this into something better.
'If you do make more out of it, please share it also.

Added particle explosions when balls are shot - now they become space dust! That added a lot of visual impact. Made few tweaks/fixes here and there.
The game is looks better, but the code doesn't. I'm going to start putting routines in SUB's and FUNTIONS now to reduce code/optimize. Need to update the sound effects, to sound files maybe.
Haven't tested this on my slower laptop, but it plays smooth on this faster one. If anyone experiences sluggishness let me know and I will tone down the amount of space dust or something.

'A bare-bones small shooter game that you can expand on.
'Follow game here: https://qb64phoenix.com/forum/showthread.php?tid=2978
'Coded by Dav, SEP/2024 for QB64-PE (Phoenix Edition)
' WARNING: THIS GAME HAS FLASHING SCREENS (not much though)
'New for v8:
' - shot balls now explode into space dust!
' - added glowing effect around player piece
' - increased background pulse intensisity
' - decreased bigball entrance time (too fast)
' - fixed superpill entrace (last ver broke it)
'Move player using arrow keys - SPACE bar shoots.
'Shoot the balls. Don't let any hit you or pass you by.
'Moving shields appears now and then to protect balls.
'See how many balls you can shoot down before dying.
'Catch green pill to increase your health points +1.
'Catch yellow pill to be invincible for 15 seconds.
'Catch red pill to get a flash bomb! ENTER to use it.
'This is a basic shooter game that is easy enough to
'learn from and expand on so you can make your own game,
'I used balls as an enemy because I had a ball SUB handy,
'and it had a colorful effect. Used it for shots and
'for the moving shield. I also used an alpha screen
'clearing method using LINE instead of CLS. This gave
'all the moving pieces a neat trailing/fade effect.
'If you miss a ball, or a ball hits you, then you loose
'a health point. If you loose all 7 health points then
'the game is over.
'If you catch green pills, it adds +1 to your health.
'If you catch yellow pills, you are invincible 15 secs.
'If you catch a red pill it gives you a flash bomb.
'Press ENTER to use you flash bombs, which will destroy
'all balls and dropping bombs on the screen.
'There are many ways to expand this into something better.
'If you do make more out of it, please share it also.
