Wow this was impressive, especially for a game jam game! Was not expecting fully voice acted competent stories that actually made me care for the characters!
The entire presentation was excellent. I loved the intro, and I especially loved how each enemy introduced themselves with full voice acting (and really well done voice acting, you guys must at least do this somewhat professionally? Pardon me if I'm not familiar with your previous works). Also the graphics and audio, all fantastic! This is probably the top most impressive looking game this jam, or at least way up there.
Gameplay seems pretty cool. I like the idea of dice battles and rolling to see how well you do. I think the game was... kinda easy though? Like I read that you want to get it to add up to seven, so I'd just grab the dice right when it was like a 2 or 5, then just gently set it down on the board. Then I would get an extra 7 damage and pretty much insta kill the enemy! This even worked on the boss at the end, I set down a 7 combo, and then 1 "6", and then there he died his long agonizing death!! Personally I didn't mind just setting down the dice as it let me progress through the story faster and it felt like I found a super cool secret strategy... but then I'm guessing that's not the way it was meant to be played. Also I never really got a feel for the different dice types other than it seems they had different face numbers. I may have just equipped too late though.
Overall though super excellent! Your whole team has done great work and this has been a highlight game for me to try this jam!!
