Guidelines for Level Rating
The following guidelines describe how to rate new levels. Since
there are many reasons why a level may become difficult to play, the
guidelines contain several "typical" reasons for a specific rating which are
separated by "/". If a level matches the criteria of more than one rating then
choose the highest rating. Please provide a demo for _every_ level you create!
The list contains a "typical" level for every rating from 1 to 9. The reasons
for rating this specific level are marked with an asterisk "*".
0 tutorial :
Difficulty 0 indicates a tutorial level. Do not use this rating yourself.
1 simple : "Sit and wait"
Almost nothing to do wrong. Look at it - solve it.* Only novice players
may need more than one attempt.
2 easy : "Welcome to the game"
Minor difficulties.* Fairly obvious traps. Straight solution possible.
3 moderate : "Adventure in a bag"
Should be a challenge for novice players. A few time-critical moves or
traps that are not too easy to avoid at first. / A solution that
requires some strategy.* / Have to be quite fast to solve that level.
4 normal : "The Far Side"
Requires some experience. Solution possible after a few attempts. May
contain some time-critical moves.* / Traps not easy to avoid. / Solution
requires considerable thinking.* / Given time or other limiting factors
are less than 150 % of theoretical minimum.
5 tricky : "Find the way out"
Virtually impossible for novice players!* Experienced players may need
more than one attempt to solve it. / Rely on special time-critical
moves* or a time-critical sequence of moves. / Rely on features of the
game that are not obvious / Contain enemies, have large playfield, are
difficult to navigate through etc. / Traps difficult to avoid at first.*
/ Rely on optimal use of time-bombs.
6 tough : "Strip Mining II"
Even experienced players will need more than one attempt: The whole
level is time-critical. / Rely on features of the game that rarely
occur in normal playing.* / Time-critical sequences essential for
solution.* / Solution requires special techniques.* / Rely on optimal
use of most of the given resources.* / Traps difficult to avoid.*
7 difficult: "The Swamp-Bridge"
A challenge for experienced players: Tough time-limit / Enemies
are a real trouble. / Rely on features of the game that almost never
occur in normal playing. / Whole solution is a time-critical sequence. /
Solution requires a few optimal time-critical sequences.* / Rely on
optimal use of all given resources. / Requires a special approach to
most of the given problems.* / Parts of the level seem impossible to
solve at first.*
8 hard : "Level 42"
Virtually impossible even for experienced players.* Extremely tough
time-limit. / Rely on obscure features of the game.* / Solution consists
of a series of time-critical sequences.* / Solution requires a lot of
optimal time-critical sequences.* / Solution seems almost impossible.*
9 m.a.d. (maximum acceptable difficulty) : "The Balance III"
A majority of experienced players would not find a solution for this
level or at least be unable to play it.* / Rely on extremely strange
features of the game.* / Need time-critical moves in order to work
with these features.* / Time-limit based on optimal number of moves.* /
Solution requires knowledge of internal representation of level data or
states.* / Solution requires series of optimal time-critical sequences. /
Whole solution is an optimal time-critical sequence.* / Solution seems
impossible even for very experienced players after dozens of attempts.*
Unrated: "Blast me too!"
The level is either unrated because its difficulty is unknown or because
none of the above ratings is applicable. / Solution is only theoretically
possible.* / Requires clairvoyance.*
Note that a correct rating for levels beyond your capabilities is not really
possible. Some players tend to overestimate their own levels - you should never
ever rate anything higher than the most difficult level you were able to solve.
A +1 _might_ be acceptable if your creation *exactly* meets the criteria of a
specific rating.
Special terms and their meaning
time-critical move: A move that requires exact timing.
time-critical sequence: A sequence of moves and not more than 4 subsequent waits.
There is a well defined limit for the number of moves between
the starting point and the end point of the sequence. If
alternative sequences exist, sub sequences may be shifted in time.
optimal-time critical sequence: A sequence of more than 3 different moves and not more
than 4 subsequent waits. Every single move has exact timing.
If alternative sequences exist all of them are optimal time
critical sequences _of_equal_lenght_!
experienced player: Player capable of solving a majority of "tricky" levels at a glance.
Consider yourself experienced if SY rates you "skilled". I mean it!
