There are so many good things about this that to list them all would take me forever. I managed to get lucky on my first run and made it all the way to the finale, so my review is based pretty much entirely on that. The sound design, art, and music are spectacular. The core gameplay is clever and addicting, and the progression is done extremely well. The only things I'd ask for would be the ability to know how much damage a roll will do before pressing attack (some dice are clearly intentionally hard to read, which, admittedly, is funny) and some shortcut for dragging POWER. One other thing too: the final boss. I lost to it in my run; the positive-to-negative and vice-versa mechanic completely blindsided me, and the dice I had weren't capable of adapting to it in any order. After the fact, I could see what combination would do it (mechanical die and some multiplication, then power die), but to have a game-flipping situation like that after 30ish minutes of building up a specific strategy was brutal. It adds something for future runs for sure, but I'm on the fence about whether it's worth it. Of course, if I missed something important with that fight, feel free to call me out!
Lots of critique there, and I'm sorry if that's unwelcome (maybe I'm just miffed about losing my first-try perfect run, lol), but I want to reiterate that it was my only semi-issue and this game as a whole is FANTASTIC. The lengthy comment is because it seems to me that you all are super into this, so I wanted to do my best to provide something of value in case you want to keep working on it. Great entry, contender for my favorite for sure, and I hope to see more of it in the future!
