Plot hole: The Toymaker throws that toy bird at the hippie version of himself. The toy goes through him because he is a hologram. Later, he pushes the soldier version of himself at the screen making it crack. How could he if the three others are holograms?
Factual error: Dinky Winks has a branding iron that says 'Dinky' when it faces out, but we should be reading it backwards. When he uses this brand, then it will be backwards.
Continuity mistake: In the scene where Juni finds Carmen in Level 4, they are on a cliff. They begin crossing a virtual bridge, then in the next shot, they are back on the cliff.
Continuity mistake: When Juni protests that he can't beat Arnold in Level 3, Juni has a silver plate on his life count. It wasn't there before the battle, and after that shot it disappears.
Deliberate mistake: After the game has entered the real world, and Floop and Minion are there to "save the day", Carmen and Juni throws seven pairs of glasses to them. But afterwords, we see there are only four pairs of glasses on Minion and one pair on Floop, which totals five.
Continuity mistake: When Grandpa picks up 2 of the programmers and makes them appear as they really are,in the next shot,the 2 he picked up are standing behind juni,and 2 different kids are in his arms.
Other mistake: If "Little Dink" isn't wearing 3-D glasses, how does he know what's going on when he tosses the branding iron to his dad?
Continuity mistake: When the programmers are teasing Juni, you see Grandpa in the mist. When Grandpa picks the programmers, you can see the camera move slightly. In other words, you can see that it is 2 different shots.
