A downloadable game

"Citybomber 4k" is a single button game for the Commodore 64. The game is based on the good old Blitz game that some of you might remember from the VIC20.

The Story:
Captain Cloudberry is back, and this time he has to fight evil Zombies populating an abandoned city far into the desert.  But as Captain Cloudberry approach the city,  he discover that he has almost no gas left and his plane slowly drops to the ground.  The airport is too far away, so his only choice is to land in the city.  To do so Captain Cloudberry has to bomb  away all Zombie infested sky scrapers, and make a safe place to land his plane.   

How to play:
You control a plane that moves across the screen. When the plane reaches the end of the screen, it drops one line down and turns around.  Below is a city with skyscrapers, and when the plane comes to close to the buildings, it will crash and game is over. To avoid collision,  you have to drop bombs from the plane, and hit the buildings to clear the landing. The bombs are dropped by pressing fire on your joystick, and when you release the button a bomb is released from the plane. It is not possible to drop more than one bomb at the same time. The level is completed when all obstacles are removed, and the plane can safely land on the bottom of the screen.

If you find the game to easy/hard you can change the level of difficulty on the main menu. Pressing "F1" will set difficulty from level 1 to 5, where "L1" is easiest with very short buildings. You can also set speed on the plane by pressing "F5".  Default is set to" L3" and "Slow Speed" , a setting most of the players can master. 

If you find this game impossible hard no matter how easy you put the settings, there is a built in trainer that you can activate on the main menu by pressing "F8"

Technical info:
The game size is only 4 kilobytes, and is a little warm up for the Reset 64 Craptastic 4k games coding competition. We hope this little game can inspire many C64 game developers to attend in this years compo. 

Buy the physical version:
The game is also available on Cartridge as a physical release from BOBR Games . It is also available in the Protovision shop. The game is a part of the "Single Button Games Collection" together with 9 other amazing single button games.

What is different from the physical version:
The physical version was made in 2019, and the digital version was upgraded in 2020.  Docster has optimized the code even more to make the game smaller.  Magnar has made a new small upgraded music player allowing us to have more modern instruments but still have a song that is no more than 5-600 bytes. Rotteroy drew a loading picture and Magnar wrote a brand new song for the loader. Rotteroy wrote an instructionspage with elements from the game as Petscii graphics.  And finally Docster onefiled and NTSC fixed everything so both Pal/NTSC users can play this little game.

Lovely. It also made me play the original Blitz game for VIC20. Too bad there's no congrats message after lv 99 and it just wraps around. :)

City Bomber remind me City Crusher for VIC-20, the best Blitz style game, in my opinion, after City Bomber 4K of course :)  


I will have a look (if I can find it :). I made my own CB inspired game where you don't crush the city but carefully fire to hit targets and then a final detonator that totals the city in one nice ASCII explosion. :D

City Crusher, original game, 1983 Your Computer magazine. 

City Crusher Arcade for VIC20 + 3K 

 I'll try soon your game. I like very much blitz style games.

Hi matey... there is a game I considered, but the jury is still out on whether I have the inclination to take part.

I do love to see other people's entries though.
