Wow, now that's what I call a post mortem! Very thorough, a perfect guide for beginners, but it still sums up all the processes that even an established translator should never forget!
I know you said you had little time and maybe it wasn't worth it for such a small project, but I assure you that no project is too small to import into MemoQ! Even just - and you probably already know this - to avoid relying on external tools to check consistency or spelling. The time you spend passing the file through external tools is probably greater than what it takes to import a project. And I assure you that I am a total noob who only has the most essential knowledge of MemoQ, but if I can help you, I'll be happy to explain the import of a basic project like one for a jam :)
Congratulations on the work and for taking the time to share your process, that's truly the perfect spirit for enjoying a jam!
