The game has some nice puzzles, but unfortunately has many bugs which make it impossible to solve the game with a 100% score.

I've never played the game, but I'm not surprised it's bugged. Just look at all the typos in that screenshot: inconsistent use of commas, a missing apostrophe, inconsistent use of spaces after punctuation, a rogue space at the start of a line, a missing fullstop at the end. Five typos in as many lines of text! If the programmer can't even type English correctly, there's no chance of typing complex code without mistakes!
