Had a lot of fun with this, the dice-keeping and ability system makes for a really interesting dynamic, and it’s easy to get hooked on one more turn. Nice work!
A couple of things I ran into:
Sometimes I double-clicked to roll and it rolled twice in a row. I wasn’t sure my first click had registered, so I clicked again. It might help to lock the roll button until the roll animation finishes.
Occasionally the dice ended up hidden under the abilities bar, so I couldn’t see what I rolled or select them.
Other than that, great job!
