no problem i saw that answer late too; developers time gives the player three stars with golden color frame, its a need for %100 i guess (because it has an achievement) examples for lost in london and lost in space: but i couldn't achieve that for lost in underground
To be honest, I never tried to do 100% in this specific game so I have no idea how to get that achievement too. But I guess it's one of those things that is almost impossible to obtain but still doable so the only piece of advice that I could give is try and try.
There is a possibility that you could get the developer time achievement in level 3, just check out the WR and do that but with a bit more efficiency I guess. I currently don't have the resource and time to test things so I'm really sorry if I couldn't give you any useful tip.
actually you helped, i will try to grind level 3 tomorrow. but i still wonder if there is a developers time in 16th level. in farmageddon party edition's steam page i found this: https://steamcommunity.com/app/259810/discussions/0/540734423763172800/ i couldn't open the chinese website though and i don't have an idea about if that page has the way in it or not. and thanks a lot.
It's possible to do it in underground level 8 on the flash version.
hello. I didn't see this, sorry for the late answer and thank you a lot. I am 0.4 seconds off so I'm curious about the way you did it. if you can explain, it will be highly appreciated.
I did it today, you can ignore this message
it's totally possible in level 8. Keep trying it in different ways and combinations. put shyrley below shaun at the end of the downhill and before that, try to put timmy inside the little space below the floor by jumping and moving foward a little and then change to shirley and pull shaun till the end of the downhill and do what I said. then you manage to put timmy and shaun after shirley and let shrley do the job by pulling shuan and timmy to the end of the level. 
it is indeed! it's been a long while since I managed to do that but I believe this tutorial is helpful as well, thank you
