Ignore the poor graphics and you will be immersed into its surprisingly solid combat system.
The unique artwork of the game captivates me, along with its comic-like frames and layout. The ability to customize the main character is a great plus, though the choices are somewhat limited.
Combat provides much more depth that it appears. The combat system is very easy to learn, yet at the same time, sophisticated. Various moves and team combos, along with the "Overkills" made skirmishes against fruit-mating robots and mimes much more lively and fun. What is interesting is that the combat is not purely turn-based. With correct strategy and timing, a player can launch much more attacks than the opponents. One of those strategies I created is "Cat-stalling", where the player can spawn the seemingly ultra-weak cat (only 1 damage) not to inflict insane damage to the opponent, but to give time for Gabe, Tycho and the player to recharge the special attacks, triggering massive specials, triple team combos - your call. Battle animations are flawless. The sight of Gabe throwing his book and blasting clowns and hobos with his abnormally-sized machine gun - or the main character scraping mimes with a rake - pleases me to no end.
Graphics is not the strongest aspect of the game. The 3D models of the characters and the environment are rather edgy - the outcome of the use of the Torque engine. But let's look at the bright side - you don't need GeForce 9xxx or Radeon 4xxxx series to run the game smoothly.
Sound is decent enough. Penny Arcade provides good-ol'-days soundtracks, in coherent to the time setting of the game. However, sound effects are sometimes repetitive, but don't worry - the addictive gameplay will overcome this issue.
Other minor issues are the inability to free roam after defeating the final boss, meaning every extra stuffs and the cases have to be collected and finished BEFORE the final boss, and the frequent lack of hints to solve the cases - but that's just me. The game is not particularly long (5-6 hours for me to finish the game, which includes collecting extraneous stuffs), but at least it's better than Strong Bad (only 2-3 hours, and yes, including worthless extras and mini games) .
Overall, the game is fairly decent for non-Penny Arcade fans and is in the "must-play" list of the Penny Arcade freaks. Waiting for the third and the fourth (final) series........
