Pretty neat little shoot-em-up with rogue-like progression.
Railgun is OP. I got to a build where I was shooting nonstop and between passive regeneration and extra ammo on rolls, I was unstoppable.
My main gripe with the game is that it doesn't particularly fit the theme of the jam. "Roll of the dice" is taken literally, as the player (dice) rolls, but you could have changed the dice with a chicken, or monkey, or whatever, and it wouldn't really change the game much.
