Earth Warp/All right!

At the start of this challenge, the text "Ellie has been writing up the story of their adventures for the children to give to the newspapers. 'Let me see,' says Jenny, taking the story from Ellie." will appear on the screen; once you've pressed Space to continue, the text "'Oh, Ellie!' she says, 'It is a great story, but there seem to be some spelling mistakes in your writing.' 'Perhaps we can help you to find them.'" will appear on the screen. Once you have pressed Space to continue for a second time, the text "Please choose an easy puzzle or a hard puzzle or a very hard puzzle" (the text "easy puzzle" shall also be highlighted, as shown in the above image) shall appear on the screen - and you will then have to use Space to select an option and press Enter to confirm your choice (the difficulty you select shall also determine how many spelling mistakes there are in Ellie's writing). Once you have done so, the text "It you get stuck, press F0/F1 to find a spelling mistake." will appear at the bottom of the screen (the usage of "it" instead of "if" is also accurate, and the key you have to press to find a spelling mistake if you get stuck yet again depends on which version you are playing); in B-Em, F0 is replicated by F1, but in !BeebIt, it is replicated by F10. Once you have pushed Space to continue for a third time, Ellie's story shall appear on the screen, with the text "Choose a word with the space bar or the arrow keys, then press Return. Press F0/F1 for help." below it - and if you had selected "easy puzzle", six randomly-selected words in it will be spelled incorrectly, but if you had selected "hard puzzle" ten randomly-selected words will be spelled incorrectly, and if you had selected "very hard puzzle" fifteen randomly-selected words shall be spelled incorrectly. Once you have highlighted an incorrectly-spelled word and pressed Enter to select it, the text "How should this word be spelt?" will appear at the bottom of the screen with a flashing cursor beneath it; once you've typed it in correctly and pressed Enter to confirm it, the text "Brilliant! Well done.", "Exactly right!", or "That's right! Well done." will appear at the bottom of the screen, and you will have to press Space to continue. However, if you type a word in wrongly and press Enter to confirm it, the text "Amina/Martin/Jenny doesn't think that is right." shall appear at the bottom of the screen, and you'll again have to push Space to continue - and if you type a word in wrongly for a second time, the text "Amina/Martin/Jenny thinks it should be: (correct spelling)" will appear at the bottom of the screen when you press Space after the game tells you one of the children does not think the spelling is right (the word in question shall also be automatically corrected) and you will once again have to press Space to continue. Furthermore, if you highlight a correctly-spelled word and push Enter, the text "Amina/Martin/Jenny thinks that word is already correct." will appear at the bottom of the screen and you'll yet again have to push Space to continue; once all the incorrectly-spelled words have been corrected, the text "'Brilliant!' says Amina, 'Now there are no spelling mistakes left.'" shall appear at the bottom of the screen. It is also worth noting that once every wrongly-spelled word in Ellie's story has been corrected on any difficulty, it reads as follows:

When you have pressed Space to continue for a minimum tenth, fourteenth or nineteenth time, a starfield shall appear at the top of the screen as both Ollie and Amina walk into view below it from the screen's left side, and both Jenny and Martin walk into view below it from the screen's right side; the text of "Your adventure is over now. 'Thank you for all your help', says Ollie. 'Remember to take good care of Planet Earth. It is the best one you know!'" shall then appear below all four of the characters. Once you've pressed Space to continue for a minimum eleventh, fifteenth or twentieth time, the text "The end" shall appear above the characters in alternating coloured letters (the letters will also change colour four times) - and if you'd pushed Y (for "yes") when the game asked if you wanted sound on the title screen, the Texas Instruments SN-76489 or !Maestro rendition of the opening bars for the serial's theme song shall then be heard for a second time, as both of the texts, the starfield and all four of the characters disappear pixel-by-pixel (but if you had pushed N for "no" when asked if you wanted sound on the title screen, the texts, starfield and characters will just disappear in silence). The game will then automatically return to the BBC Micro command prompt or whichever version of RISC OS your Archimedes is running (the latest version of that OS at the time the game was released was 3.19 but it ran on all subsequent versions until 3.71 in 1997); the Look and Read series also went on to continue on the RISC PC with Spywatch in 1996 and Captain Crimson in 1997, and eventually concluded on Windows with The Legend of the Lost Keys in 1998.
