Fun idea for a memory game. Highest score I got was 87 before I lost my nerve.
Art is very well coordinated and pleasent. The music goes well with it too.
As mentioned, its a good idea for a memory game, and I found it had good replay value. Game matches well with the Jam theme too.
For improvements, some work needs doing on the UI/SFX (as I am sure you are well aware). Also would be nice if the game stored your highest score. Could set that up quite easily using PlayerPrefs in Unity.
Overall, good submission. Had fun playing it!
