- Breather Boss: Gantu, who is the Final Boss, is relatively easy to defeat compared to the first two bosses of the game.
- Ensemble Dark Horse: 621 and Dr. Habbitrale, the former due to being one of the first experiments other than Stitch to be introduced and the latter for being the inspiration of Dr. Jacques von Hämsterviel.
- Goddamned Bats: The Buzzers, which are red wasps that won't stop attacking, even if their hive is destroyed.
- Hilarious in Hindsight: The film the game was based on happened to be released on 6/21/2002.
- Most Wonderful Sound: 626 saying, "Yee-haw!" after picking up Red DNA.
- Player Punch: During the first two sections of the game, 621 taunts you whenever 626 is killed.
- Special Effect Failure: The graphics are rather crude and lackluster, especially for a PS2 game released in 2002; IGN's review noted the low-resolution or non-existent textures and lack of proper lighting. The cutscenes in particular have some rather stiff animation, which is especially bad knowing that this is a Disney game, and parts of the characters' models clip through sometimes, such as one of 621's spines going through his head.
◊ - Suspiciously Similar Song: A lot of the background music is very similar to music heard in Shadow the Hedgehog. This is because both games use samples from the stock music library Electric Ghetto released by Big Fish Audio.
- The Problem with Licensed Games: It is the most ambitious of the tie-in games, being a prequel to the events of the film and also being one of the first works to introduce one of the other experiments. However, it was criticized for rough gameplay, camera issues, and weak graphics compared to other PlayStation 2 titles of the time. The events of this game were also later Retconned by the events of Lilo & Stitch 2: Stitch Has a Glitch.
- They Wasted a Perfectly Good Character: The Grand Councilwoman was going to have a role in the game, but she is only seen in a building advertisement in Pizton and her one cutscene got cut.
- They Wasted a Perfectly Good Plot: The 700-Series (or just 7-Series) experiments are seen being developed, but they're are not seen in any other part of the franchise. Then again, considering that Jumba has made only about 630 experiments in the later-established animated canon, it wouldn't make much sense to have the 7-Series appear.
- Unintentionally Sympathetic: 621; we're supposed to not like him because he's antagonizing Jumba and 626/Stitch, who would eventually reform in the film. However, 626 is a Villain Protagonist in this game and 621, who only desires Jumba's approval, gets verbally abused by his own creator while 626 gets all the praise for being the superior genetic experiment. With that in mind, it's no wonder why he strikes out on his own to get DNA and mutate himself.
