We have 20 educational Flash games, mostly quite straightforward games like drag-drop, fill-in, etc. that we need fixed. They were made a few years ago, but have various errors, like we need to change text, headings, add sound, etc. plus sometime programming error. It is difficult to estimate what this will take of time, as some games may take minutes and others hours to fix. We are also looking for more educational games. If you are offering games, please show us sample. For the job the easiest is that you base the bid on 20 hours work.
