Bart's games aren't always difficult, but they are always fun. Probably won't play this more than once, but it was enjoyable to get through (about 5 to 10 minutes).
Please, please, please, build out this game more! So much can be done with it, as others have suggested. Add more puzzle elements, maybe allow the player to pull, push, or carry letters to try different combos and perhaps introduce multiple different solution paths.
Zidanegage... I wiki zidanegage... nothing pops up, strange. I did however find an entry for "implementation" (with one 'n' at the end, as opposed to your spelling). I don't usually troll, but your comment annoys me just so. Are you trying to be funny, or smart? Did you really look up "implementation" and not find it? Arggggg!
Wow. What an awful experience. How about a tutorial? Everyone, check out an old-school free multiplayer game called Continuum. This is a fun game with an old, established community.
Great game, more difficult than most difference games. It is buggy though... some valid clicks register as errors instead of found difference. Need to fix this, as it makes the player start from the beginning every time there's a loss.
This is ridiculous. If there's a game that truly tests one's brain, this is it. ADD sufferers may have an advantage. Cheaters should be banished forever.
