Nice idea to have a collection of mini-games and the fast paced change between them! I really like the overall concept. Here is some feedback of things you might want to improve:
- Make the time to read the instructions for the next game a bit longer. I liked the fast pace, but quite often I was not able to read everything.
- I experienced a bug between the games, where one game was announced and but then it immediately switched to the next one.
- Add music and sound effects.
Still this is a very solid entry and a good start, especially when you used Phaser the first time. Wish you good luck with it!
