My children have been using this for ages. It is a wonderfully simple game.
I have always thought that the best games for children are the ones where they learn something without actually knowing that they were learning anything. That’s what bugband does. Notes appear on a stave as a series of bugs. They crawl along and you have to tap the right note on the keyboard that corresponds with the note that they are crawling on.
It couldn’t be more simple, but I’ve watched my daughter play with this for at least half an hour at a time, and be really pleased when she gets up a level.
Really worth a try for children and adults too.
