Classic game. Its fine, just some details:
- many pieces look similar to each others, so its hard to identify the pairs.
- The clock is running to fast, i think it does't counts time as it should
- The score screen is glitched and everthing appears as 9999999999999.....9999
- I think it would be cool if you had a way of knowing which "styles" you've already passed
Good game, keep it up!
