Very fun to figure out the best strategies! I spent actually quite a while playing this lol, I became a bit addicted.
A couple thoughts (I really like this game so if you continue working on it here are some suggestions )-
It would be nice to have an ability to speed up time, maybe by holding the screen to make the cycle go faster because sometimes I'd just be waiting for the cycle to loop again to get my rolls back.
The upgrade by one power was WAYY overpowered. I like the idea of it, and I also like that it's product dice can be used in the clone upgrade, but being able to put it back through the same upgrade made things way too easy to just choose whatever numbers you want.
As I got better at managing the timers while Solving the quest, I started craving something a bit more challenging. What you had for the jam was perfect, but you have an insane amount of room to expand this if you wanted to, whether that be with different operations other than just addition to make the sums, perhaps done by using special dice (for example subtraction dice that subtracts the dice to it's right from the sum on it's left), or maybe you could even add in semi-random events to keep the content fresh for longer.
Anyway as you can probably tell, this game got me unreasonably excited, there are so many directions you can take it. Good stuff!
