Despite the fact that you had less than a day to complete this, you made something and it works! Good job! It is definitely not the greatest game ever made, but I enjoyed the 3 or so minutes I spent with it.
The was really strange at first and I just kept dying as I roll enough dice to kill all the cards, but after reading the description I understood that I could knock the king dice away, which made the game a lot better. With that being said, I think that the game is a bit unbalanced, as just shooting dice at the king dice will basically make you invincible, I think a compromise which might work better is still being able to knock the king dice away, but not giving it the ability to kill cards; this would force you to make trickshots to both kill cards and save the king at once, which might be a bit cooler [if this is too much, perhaps disabling normal dice collision would balance it out]. I like the ability to change sides as it makes it a lot easier to track down specific spots; perhaps a more intuitive design would be to have the play are be a circle and to move the dice cup around the ring based on mouse position.
The presentation is nice, but the song starting over and over was very grating, I don't think that torture should be a punishment for dying in a game ;w;. Just letting the song play even after you die might be a better idea in future. Otherwise the graphics are simple but cute, the pastel background is nice.
Overall just a fun few minutes :) Wish you guys luck and thanks for the game!
