The shareware version of CHARLIE II contains six levels, of which two
are hidden (indicated with the question marks). The objective of each
level is to collect coins and diamonds and then find an exit. Some
levels have a secret exit which leads to a hidden level.
From the OPTIONS menu, you can select the difficulty: EASY, NORMAL or
HARD. To complete a level, you must collect at least the following
percentage of coins and diamonds, which varies per difficulty:
| Difficulty | Required percentage of coins and diamonds |
| EASY | 45% |
| NORMAL | 60% |
| HARD | 75% |
Because the amount of items is different in each level, just keep
collecting them until you see the message "Find the exit!". If you leave
a level without the required percentage of coins and diamonds, you will
have to retry it.
The hearts at the top left indicate Charlie's health. The number of
hearts at the beginning depends on the selected difficulty. A super
heart is hidden somewhere in most of the levels.
Just like in the original Charlie the Duck game, Charlie can beat most
of his enemies by jumping on top of them, but some can only be defeated
using a shield. Items are hidden in the yellow crates.
In each level, you can find the letters to spell the name "CHARLIE". If
you find them all, Charlie receives an extra life.
Each level has a check point. After touching it, you can start there if
Charlie loses a life. However, if you exit the game and start again, you
will always have to start at the beginning of the level.
When you start playing, you have to select file 1, 2 or 3. Your progress
is automatically saved in this file. Normally, you can't play levels
you have completed earlier, but after completing the entire game
(complete version), you may choose any level to play. Only after
reaching 100% for every single level, you may add your total score (of
all the levels together) to the high scores!
