Stick it to the Man is being hailed as a "spiritual successor to Psychonauts", a title that I have a few problems with. Sure, it deals with similar subject material and has a similar design aesthetic, but that's like saying "EVE Online is a spiritual successor to Galaga". The games are barely similar, the matching artstyle is the closest you're going to get.
SITTM plays more like a graphic novel with limited adventure game puzzle solving mechanics. You'll get that nice rewarding feeling from putting the right item into the right slot, but the majority of your time will be spent patiently listening to every mind-reading audio file, regardless of whether or not the puzzle is already solved. You will feel a compulsive need to read EVERY mind you come across, even if it's unnecessary, and you probably should because there's an achievement for it. Ultimately, while having the game come to a stop every 30 seconds so you can read a new mind does indeed break good, natural gameplay flow into splintery pieces, I immediately forgive it. The game is never boring, and no amount of dialogue could stop be from being impressed by the beautiful design.
Well... I SAY that, but I never actually finished the game :/.
The game plays in 2.5D, and I have to say, I've played with better platforming controls. The protagonist can swing to designated areas and manipulate certain pieces of backdrop, but regular jumping to certin platforms is finnicky, and you will find yourself slipping off quite often if you didn't jump PERFECTLY.
I would have rated this game way lower, but it's rare to find a game that makes me laugh so damn hard. The game is genuinely enjoyable, and gets a high reccomendation.
