This felt like a cool boss fight from a game! I really enjoyed dodging enemies initially and shooting at the dice while trying to survive. You did really well to create a cool vibe for the game as well with the music choice and color scheme.
For being created in one and a half days I think you did really well to create a complete game experience (even if it only had two levels). I'd totally play a more developed and polished version of this if you ever chose to make one! Great job!
