Welcome to the game. Once Pat has appeared on the screen, you will have to start walking to the right and collect a stamp; once you have done so, you will have to jump up to the second step of the platform, and collect three more stamps. You'll then have to jump up to collect a letter - and once you have done so, you shall have to continue walking to the right to collect a parcel and three more stamps. You will then have to jump onto a windowsill to collect another letter; once you've done so you shall have to drop back down to the second step of the platform to collect another parcel and jump onto another windowsill to collect a third letter. You shall then have to drop back down onto the second step of the platform to collect an eighth stamp, and drop down onto three more steps of the platform to collect five more stamps in turn - and once you've done so, you will have to jump onto a wall to collect two more stamps and a fourth letter. You must then drop back down to that fifth step of the platform to collect a sixteenth stamp, and jump up to a third windowsill to collect a seventeenth stamp and a fifth letter; once you've done so, you will have to jump onto a fourth windowsill to collect a fourth parcel, drop back down to the fifth step of the platform, jump up to collect two more stamps and jump onto a fifth windowsill to collect a sixth letter. You shall then have to drop back down to the fifth step of the platform, jump up to collect a fourth parcel and jump onto a sixth windowsill to collect a seventh letter - and once you have done so, you will have to drop back down to the fifth step of the platform, continue walking to the right past a checkpoint postbox (whose flag will go up) to collect a twentieth stamp, and jump onto two swimrings in a pool of water to collect two more stamps, an eighth letter and a fifth parcel in turn. You'll then have to jump onto another platform to collect a ninth letter and a twenty-third stamp; once you have done so, you will have to continue walking to the right to collect a twenty-fourth stamp, and jump onto another wall to collect two more stamps. You will then have to jump onto a seventh windowsill to collect a twenty-seventh stamp, jump back to the left onto an eighth windowsill to collect a sixth parcel, drop back down onto the seventh windowsill and jump up onto a ninth one to collect a twenty-eighth stamp - and once you've done it, you'll have to drop down onto a tenth windowsill to collect a tenth letter, drop back down to the second platform and jump onto a vertically-moving platform to collect two more stamps once it has moved up. You'll now have to continue walking to the right onto the second step of the second platform to collect nine more stamps, a seventh parcel, and an eleventh letter, pass a second checkpoint postbox (whose flag shall, again, go up), and jump up to collect a twelfth letter; you shall then come to Jess.
Once control has been switched to Jess you'll have to walk to the left, climb up a drainpipe to a gutter, and walk back to the right to collect seven more stamps and a thirteenth letter; once you have done so, you will have to jump onto a third platform to collect an eighth parcel and a forty-seventh stamp (which will lower itself into another pool of water as control is switched back to Pat). You will then have to jump onto the third platform to collect a forty-eighth stamp, and jump onto a fourth platform to collect two more stamps - and once you have done so you will have to jump up to collect a fourteenth letter, continue walking to the right to collect three more stamps, and drop down to the second step of the platform. You shall then have to jump onto a third wall to collect a fifteenth letter, and continue walking to the right to collect two more stamps; once you have done it you will have to jump onto two more windowsills (to collect four more stamps in turn), jump back to the left onto a thirteenth windowsill to collect two more stamps & a sixteenth letter, and walk onto a blue button to activate a bridge (over a third pool of water). You'll now have to jump back onto the twelfth windowsill, drop down to the third step of the platform, walk over the newly-activated bridge (to collect two more letters and a ninth parcel) and jump onto a fourteenth windowsill to collect a nineteenth letter - and once you've done it, you will have to drop back down to the third step of the platform, jump up to collect a tenth parcel, and jump onto a fifteenth windowsill to collect a twentieth letter. You will then have to drop back down to that third step of the platform as you come to Mrs. Goggins; once Pat has met up with her, the text "Congratulations, you have succeeded!" will appear at the top of the screen with the amounts of stamps, letters and parcels you collected out of the total available below it and the text "Well done!" below them. You shall now proceed to Level 1-B.
