This was so fun and engaging to me! There's a lot I liked in this one. The movement just felt good, you feel you are in control but not totally, and that's a type of chaos that I like. Loved the idea of not immediately killing the player when the ship exit the play area, but rather starting a countdown: not punishing and fun to play with. And most importantly I loved the game progression: I think I played so many waves that at that point I was totally OP, but the fact that dice keep coming gave me a reason to keep playing.
So, in the long run I think the game needs a little bit of variety, both in enemy types and visuals/music. But considering that this was made in 48h I think that this is a very good product for a rewarding and fun experience.
The dice rolling theme is not particularly strong but it's there, so hey!
Oh, one final comment: I think I am more and more into minimal aesthetic, and this game confirmed this trend for me. I liked the art :) If you want, you can try my submission to see how I made a game with the same theme (space) but a completely different concept!
