I've been playing this game on a PS2 emulator, and I'm currently at the balloon section.
I think I've hit the jackpot of shitty games, Sup Forums. You really need to play this because it really is the magnum opus of movie-licensed shovelware. Shitty controls, shitty platforming, obnoxious sounds from George every five seconds, terrible design, and double-jumps require that four x-presses.
The first thing you see when you load up the game is a standard advertisement for Universal Studios, except the audio is literally earrape. Every level is interrupted by a cutscene from the 2006 movie adaptation, and the only audio that plays in those clips are the characters' voices and maybe some music every once in a while.
The gameplay is...well...imagine a shittier version of Donkey Kong 64, except it's set in an urban environment for most of the game. Every level is just you following the orders of some female narrator, who constantly says "GeT tHe idoL, gEt ThE iDol!!!!!!". You have to run across one area of the map to another in order to collect these idol things, and you literally backtrace around an entire map on one of the earlier levels to "GET THE IDOL, GET THE IDOL!!!! GET THE IDOL!!!". I swear to fucking God, I don't know what it is about her voice, but it sounds so fucking obnoxious to me. Many of the levels that I've played so far require to complete some sort of minigame, and they're nothing really special. The only minigame that I find vaguely memorable is the bubble bath minigame, which simply involves popping bubbles.
Oh, and did I mention that you could interact with a lot of stuff? I would say "everything", but that would be ignoring the game's incompetence. You could interact with a bunch of shit and listen to Curious George obnoxiously scream five-hundred more times (or in one case, listen to him beatbox).
The only reason I'm playing this game is because I was just reminded the other day of how I actually grew up with this shit. Thanks, Vinesauce.
