Wow, really fun game! For a game jam game, I'm really impressed at the professional-looking presentation: the graphics, animation, aesthetic, and feedback/juice are very nice and appealing. Couple that with the very chaotic and addictive gameplay from a great concept and I was having a blast trying to keep myself alive.
I definitely did have a bit of a confusing time at the start: I completely forgot that the jump button existed and just figured that the only way to avoid damage was to just be quick and decisive with whatever the dice grants you. It actually was kinda fun to play like that, though ultimately futile given the threats that come up, so I'm glad I eventually realized that there was another option for defense. Curious whether anyone else had that experience: I feel like it was natural to assume due to the focus on automated movement and random dice, but maybe I'm just dumb.
Some feedback more to do with the game rather that my foolishness were:
1) I found it very difficult to keep track of resources like health and such. For some reason, I thought I was being hit constantly and about to die, but I'd somehow make it out with higher health than I thought. I think what led to that confusion is that, while the screen shakes and plays a sound when you get hit, it also shakes and plays a similar 'bad' sound when it rolls the dice, which felt very unnecessary and sending confusing signals.
2) In regards to the upgrade system, I had no idea what the dice upgrades were. The muscle upgrades were very clear, but the dice updates...did they like add to your pool or something to make it have a higher chance to appear? I had no idea.
Would love to see this game get expanded upon as it feels like it has a greatly constructed core: some more enemy types/weapons/dice, a story/goal to progress on, and so on, it'd be great!
