"Made" was trickier than I thought it would be initially. There's not many words that begin with "made". It can keep momentum a little easier if you're not too concerned about maintaining precise compound words, and instead just steal the last few letters to create the next word if you're stuck. But up to you.
Hyphenated words and two word phrases are acceptable as well. Using the end of the word to make up a new compound word is also okay in a pinch. Otherwise it just becomes a word chain like the game that already exists. (made-up, made out, made good)
