I really agree with the first comment. The idea is cool and the set up is interesting, but its really difficult to play and doesn't feel super great to handle. It'd also be cool if the dice affected something about the ship more than just the amount of ammo (like fire rate or bullet type). It feels like the start of something really solid, but I had a difficult time making any progress in the game.

A solid start to a game. My biggest problem is because of how slow you move combined with yours and your enemy's bullets being the same speed you can't try and shoot an enemy without dying yourself.  Id make the player movement more snappy so you can shoot and dodge better.
