Did Shnorr broke RSA ?

GullCode



A recently published paper by a reputable German mathematician and cryptographer has garnered widespread attention for its claim to have destroyed the RSA algorithm. However, many people are skeptical. Join us as we discuss the paper’s content, the proposed methodology, and the public discussion it has generated.

KrampusHack 2020 FINISHED

And here is my entry: a space shooter !

RazorCrest (click here to download)

Task (for NunoMartinez):

Finally, here it is my wishlist:
* Fast game. I mean that you can play a complete “play” in few minutes.
* Minimalistic graphics. Don’t make them complex.
* Finally, select one of your own wishes.

How I achieved the rules:

  • Fast game. I mean that you can play a complete “play” in few minutes.
    ===> You start it you play
  • Minimalistic graphics. Don’t make them complex.
    ===> Only 4 sprites and they are very basic due to my drawing style, the rest is only circles, triangles and rectangles
  • Finally, select one of your own wishes.
    ===> Particles !!!

How to play:

-up to start moving
-arrows to move the ship
=> more XP = quicker
-use the mouse to aim and use mouse button or key CTRL to fire
=> more XP = more and better bullets, better accuracy
-green monsters are light enemies that are just traveling here
-yellow monsters are aggressives enemies that are targeting you
-red monsters are very aggressives enemies that are targeting you, and they are more solid
-the more you kill the more power you have to kill
-hitting the walls or being hit by an enemy makes you loose life and XP (thus fire power)

Building from source:

-Go with a shell into to SRC/KRAMPUSHACK2020
-Type make
-If it works move the binary to ../..
-If it’s not working, come and complain here :-p

Hint for finishing

-Because the ship can speed up does not mean you should use it all the time
-Kill as much as you can on first levels so you have the firepower for next levels
-Use thrust/slow down/side jumps to avoid enemies while shooting at them
