This was a pretty fun game. Really simple mechanics and choices but kept me wanting to keep trying for infinite cookies (I couldn't get there though).
Games of chance like this are quite hard to get right with only a few days of balancing, and I feel like there could be a lot more tweaking of the upgrade cost scaling, number of allowed re-rolls, chance of getting a bad upgrade and also giving the player more options each round so that they're in more control of their risk management. This would make each roll feel more exciting and the player feel really good about their choice.
But again, what you've made in a few days is a really great game and take on the theme. Well done!
