i personally think lvl 18 and 35 was the two of the most interesting ones, if you can solve that two lvls you will gain enough the spirit of this puzzler to go through the rest of its levels
if you have played this game long enough you would realize this game is pointless, whether you have found a strategy to defeat the computer or not, the game is pointless.
altho the graphic is great
