Really cool idea well executed!
The game looks really pretty and is really fluid. I didn't find out about the non-used dice affecting the performance of the action until after reading another comment on here, it totally changes and improves the game! I do wish the music would change inbetween matches as it seems a bit strange that is changes only after you start a new game and not after you start a new match. The only thing I didn't like about the presentation apart from the unclarity of the combining dice is the death tone, it just sounds horrible and makes me want to cry, pls chang thx.
I like the gameplay loop and the combining dice are a great idea. I didnt love that the build changed completely every match, but it should change a little bit to prevent the game from becoming stale/you being stuck with a great/horrible action build, it might be a good idea to change just 1 dice action (or swap 2) every match to spice things up.
Not much else to say really, a really nicely done, nicely polished game! Thanks and good luck!
