Great work for a jam! I finished the game (one act right?) with the Samurai. Didn't try out other characters. (You made a roguelike and have three characters!)
This game offers a unique forging experience. Thinking about how best to combine the dice symbols and elements, the game really comes alive in the forging cells. I really would have liked to have the element reference during forging, so I took a screenshot next time around, and was using that.
The difficulty curve is pleasant to work with: I wasn't daunted by the initial battles, but the later ones became more challenging, so good job there.
Some of the mechanics didn't work the way I thought they would. For example, when an attack is blocked, the special effect, like Dream still goes through. And the attack also counts towards Critical even if it's blocked? Maybe these are ok (although I feel they should get fully blocked). Just that I didn't expect it.
The "Bug" element is really cool in particular. I started "holding" a dice even if the symbol didn't match, because it counted towards the "Bug" bonus. This suggests there's good potential in the core design for even more mechanics.
The rerolls are helpful. Is there a (planned) economy to them? Or I can simply keep rerolling each time?
The symbols. All I understood now was that you have to match them. Is there a pattern to them depending on the enemy? Maybe that's something to think about.
When there are multiple enemies there's more matching happening initially, which is great. But as the enemy count goes down, there are more idle turns where nothing matches. The forging should address that to some extent, but still.
Some improvements to UX would surely help. (Not counting this as a minus or anything for this jam. It's already quite good. Just notes for future.) (1) The element reference as mentioned above. (2) Once I forge a die it's frozen, which is sort of ok. But I can't view it again for reference during forging, which is a pain. (3) Being able to view the progress map during forging.
You guys certainly have something here. And I can see in the notes here you're planning to expand this further. Wish you the best for that!
