The pixel artwork is GREAT but the enemies move WAY too fast, I literally can't hit them because I have to guess where they are. I'd play this without the dice mechanic, it's just a hindrance and adds nothing to the game.
I'd say, both? the dice (powerups?) give no explanation whatsoever, and just felt like an annoying and random pause menu for the bullet hell gameplay. The random reload would be fun if the goal was to save ammo; here, it just felt like a gimmick gun from a different shooter.
