These games have become a guilty pleasure of mine as a point-n-click fan.
Sure they may not have the depth and complexity as some other showings in the genre (another reviewer mentioned scriptwelder whose games I love), but they're a consistent light-hearted showing that never fails to kill a bit of time. The prolific release schedule is excellent for keeping oneself occupied between the more ambitious endeavors by other authors on the site. The cartoony graphics keep with the fun atmosphere.
A bit more effort into making the song loops just a bit longer and taking some risks puzzle-wise, plus reining in the odd 'pixel-hunt' problem (the available walkthroughs are a great help but it's always a little disappointing to have to resort to it) and these games could really shine. As they are, they're a perfectly fine little diversion.
