This is an amazing game, but there are a few things that could make this game so much better.
1. I think something this game really needs is a difficulty setting. I have played this game for absolute ages and never gotten to the bee boss. I think a difficulty setting would be amazing to give players a challenge while still letting them be able to see the boss.
2. I would like to know how the heck you are supposed to get the two secret dice. Is it just rng? If so please change that because that could get really frustrating.
3. Just add more dice, enemies, and bosses. This could evolve into a fully fledged game. Heck, you could even add a story. This game has amazing potential.
In Summary: I think you should add a difficulty setting, make a better way to get the two secret dice, and start making this into a fully fledged game with more dice, enemies, bosses, and even a story.
