This game is fun. It has a nice aesthetic and some good juice ("POWER UP"). I gave it a few runs, and even though I think the max time is a bit too unforgiving at times, I had a blast.
The only feedback I would give is that I think the theme is underdeveloped. When you are killing so many objects in quick succession - each individual roll has little impact on the overall gaming experience. If each kill returned 3.5 seconds (the average of a D6) then I think the player experience would be essentially unchanged.
If you have time, I would appreciate your feedback of my game.
