Ah, when I said "the player should decide when to reset" I meant that sometimes there's an in-game way of resetting things back to a default state or reverting back to a checkpoint without needing to select an option from a menu (which I didn't even know I could do). Like, maybe if there were a prompt in the top corner of the screen to hold a button on the keyboard and reset that way?
Looking back on my previous point of mine, I understand now why you decided to make the dice explode and respawn after a few throws because even a tiny tap of a throw can make the number go up. Dunno if you'd be able to change how fast the number goes up after it's been thrown but from what I could see it appears to be based on how often the die makes a quarter of a revolution which I suppose makes sense as well. Maybe lean into that and allow the player to influence how fast the die spins by having it bounce against walls and other surfaces? Perhaps they could be able to "curl" the die by holding the left mouse button and drawing an arc with their aiming reticule as they prepare to throw (having the player position the reticule further away from the playable character would be a better way of controlling power as well)?
Whatever I say )I'm just spitballing random ideas now) feel free to go with whatever direction suits your game's needs. I didn't focus much on positives, but did value my time playing your game and there were some very interesting ideas that I think could be experimented with in great ways! :)
