Neat little snare beat for backing music. Visuals were pretty nice as well, reminded me a lot of asteroid's vector graphics conceptually, but with a neon oomph. Gameplay, however, was a bit offputting, though still fun in its own way. The concept that the dice are moving towards you and trying to kill you is fine, but the ship has a very slow acceleration, very fast deceleration, and no momentum to speak of, so it's rather unintuitive to control the ship. Also, since there's no penalties for missing, you basically play with space held down the entire time, to get the best fire rate and help you dial in the angle needed for a shot (since unlike your grid-locked opponents, you float freely through space), so removing that and just making it automatically shoot would probably be a little better.
Conceptually, the idea for only being vulnerable when specific faces (I believe it was any even face) was neat, but the dice don't actually follow the progression of a six-sided die, instead randomly flipping between any given face, so there's no real strategy in manipulating the dice to move specific ways and force them to show green faces; it's just hoping that a green face will show up when you're shooting at them. They also have a bit of an erratic movement pattern, where they can jump forward an extra space shortly after moving, and it almost seemed in time with an audio cue, but I can't be 100% sure of that (I did like that, either way, because it made it more interesting, but when I was slowly backing away from one and it suddenly jumped forward two and ate my ship, I got a little salty about that, since it was the first time I saw it).
The waves just getting larger and larger, throwing more dice at you with each wave, though, was uninteresting, and the primary point I'd focus on changing if you were to develop this game further, with the controls scheme right behind it (if I'm fighting the controls as much or more than the enemies, there's a problem, hah). I'd also work on getting the dice to properly respect the orientation that they're travelling and change face accordingly, so that each tile shows the die flipping to the next side as it rolls after your ship. Otherwise, a neat little Game Jam game.
