So, the art style and overall theming was incredible. This one feels more like a tech demo, which is fine, this is a game jam. But it would be a shame if there was never more to this. I'd like to see this as a full game or some other full game from you that uses this artstyle, it's great!
Regarding the 'Simon Says' minigame, it would be a good idea to start with two rounds that have the colours blink slowly and gradually speed up. That would allow people to get what they are supposed to be doing.
