Congrats on finishing your game.
I'm not entirely sure how the combat is resolved. It was unclear what effect each die face had on combat. Sometimes a mushroom would take out a water in 1 hit, sometimes it felt like more? And do the heart dice effect the element dice? What do those do? I was very confused.
Also, having elements with no interaction (fire/mushroom, water/tree) felt kinda weird. There were a lot of rolls where I couldn't do anything meaningful with my rolls. Having some way for players to pull off moves that feel good might make the game feel more smooth overall. But that's just my opinion, and I'm not sure I understood the game correctly in the first place.
What I really appreciated about your game was the very clear messaging about what to do next. That's something I didn't do well in my game. You made it very clear that a player should roll or assign or do something specific by replacing the roll button with text or another option. Well done.
Overall, cool design and I'm happy you were able to create something like this in 48 hours. Keep making games!
