Really appreciate the time to create three different characters each with different abilities and tell a story!
A few things that I think need to be considered next time if you'd like to step up your game to the next level.
1. It wasn't super challenging, it felt like more of an interactive story than a fully fledged game.
2. A lot of the audio clips sounded quite low quality which was a bit of a distraction.
3. The backgrounds were quite inconsistent, although I really liked the parallax effect you added. The first background was just plain blue though so felt inconsistent.
4. The story felt a little... all over the place. I was a little confused where and what was going on. I think that this could be clearer with a very clearly defined start, middle and end.
Overall
To say the very least, this game was super creative, a whole load of ideas all packed into one that I hope you learnt a lot from - that's what it's all about!
