Congratulations on finishing the jam!
It took me a little bit to get used to the controls, and was incredibly difficult at first. But after I understood how best to go about moving and locking in the dice I gathered up to 88 as my high score. A lot of the difficulty came in the limited time I had to handle the dice before the next one dropped. Some additional time before the next dice drops and possibly limiting it to only a few at a time would help greatly smooth out that difficulty. Additionally, maybe consider adding in some time before the die fully locks in so the player could recover dice they weren't able to get to initially.
Decent sound effects, but the loop on the main theme could use some variation as it got stale pretty quick.
Great work!
