This game has undergone some significant changes, such as:
Changed title screen, added hacker initials (the original copyright is not affected).
Changed the palette at all levels of the game, all levels are fixed. Added a fork on each level.
Fixed the menu on “game over” screen.
Ladder in the game is now infinite, allowing you to explore all corners of the levels.
Start with 3 lives, after game over - 3 lives too.
For extra lives you need to collect 30 letters “K”, instead of 50.
Final word “Congratulations!” is fixed, unnecessary word “NEXT” was removed.
As you know, the game has become more interesting and playable, unlike the original.
Unfortunately, this is a bad dump of this game, so you’ll view some graphic bugs on some emulators in certain cases.
Thank to @Lomax for hacking pointers on the title screen. And @Mega-Dog - for level editor “FatCamp” (not perfect, but good).
And thank you for playing.
