I love me a good bullet hell shoot 'em up, and this definitely feels like one! Controls were solid and it felt pretty satisfying to mow down rows of enemies in seconds.
I get this is RNG based, but that is it's on thing and this doesn't really seem to fit the theme. There's definitely better ways to implement that, like getting randomised upgrades depending on what number you roll or something like that. I also didn't like how it was near impossible to dodge projectiles simply because there way too many on screen at once.
Overall, it's an interesting concept with potential for further development. Hope you keep going with it after the jam!
