The Kissing Bandit is extremely linear, and basically runs on rails, with little real interactivity. What saves it, tough, is the hysterical writing, which are sure to make you smile throughout the game.
There are no puzzles as such, and you don't even have to pick up anything during the game (but do examine your inventory!). While many 'original' verbs are implemented, several items mentioned in the room descriptions are not, and the autocompletion could be smarter. For instance, typing 'climb' outside a tower offers the not-so-helpful (but somewhat amusing) completion 'climb (the maiden)'. The author does acknowledge the somewhat spotty implementation, caused by lack of time before the submit deadline, and it would be nice to see an expanded and improved version released.
All in all, I think the humour and the overall cuteness of The Kissing Bandit does make up for some of its shortcomings, and since the game only takes about 10 minutes to play, it's well worth spending those 10 minutes.
