see level 41 of pi.dat.

there are two solutions, one which gets stuck in an infinite loop and one which does not.

if one plays with a perfectly optimized route, level 3 takes longer than level 2... but the bold time for level 3 is greater than the bold time for level 2.

as far as i know, this is the first time the multi-tank bug has been used in a level; i am unaware if it has even been characterized before. it exhibits many interesting properties, which are explored in subsequent levels.
also, 85 is possible.

88 is possible.

one of my scores on this level was 1339 (score, not time).

this level can be solved in 4 seconds.

the original version of this level was tw-compatible, but i liked this one more.

for higher scores on this level, the mouse may be useful. at the moment, this will not work in tile world, because of a bug in handling mouse moves.

the title may be misleading as to the level's hardness.

this is probably my favorite level.

this level was made first, and then the next three were supposed to correct a bust present in the previous version.

when resetting a coordinate a second time, don't forget to make sure the corresponding tile at the bottom of the map isn't blocked.

x-(14,3) x-(14,2) x-(21,2)

this level would still be solvable if the time limit were 100 instead of 999. it would also still be solvable if the chip were removed.

90 is possible in an odd sort of way.

except for the title, levels 20 and 21 are identical... or are they?

the fast solutions are only possible in mscc.

solving this level should result in a negative score in mscc due to an overflow in the score arithmetic, whence the title.

the time limit on this level may be too low.

the time limit is generous, but this level is still quite long. it may in fact be the level with the longest shortest solution in a 'nontrivial' sense (i.e., that requires continuous thinking by the player).

irritatingly, i missed the spelling error in the title of this level before i released it. what's worse is that i had actually corrected it, but then uploaded the wrong file.

a fix of the bust in level 22, i hope.

unless i made a mistake, this one should be impossible. three cheers for slide delay!
