Finally, after lots of testing and playthroughs, a new mod is ready for download. The theme is Pop Culture, from movies and music, to books and nursery rhymes. Sorry, it's only in English (nothing is translated in other languages).
First, you're going to want to dowloand Daxar's liTools 0.3.7 here and follow the instructions to the letter.
Before you continue, you'll want to make a backup copy of the Little Inferno.exe in the liTools folder, so that if you want to do any other modding, you can use that backup copy and set aside this copy you'll soon be updating with my combos.
Next, download the new combos here.
Unzip the folder inside the liTools folder, then drag-and-drop popculturecombos.pak onto the modManage.exe program. That will update the game, and now you can open Little Inferno.exe from inside the liTools folder.
I'll respond later with other comments, like how to make your own combos.
