Just played it! :) Here are miscellaneous comments.

1. I see on the game page that you put a conscientious story; it is nice to have some coherent context/story that comes with a game.
2. The graphics are varied, neat and have their own personal style. (I guess you were at an advantage there since you are a team with partial specialties, but anyway!)
3. Enemy types, especially Asian girls with red umbrellas: somehow reminds me of Streets of Rage. X)
4. I like the very tactical idea that you have to pass a die under the umbrella and then throw it!
5. I see a huge gameplay problem: it is way too easy to generate a lot of dice and then wait for enemies to run into them… There should definitely be some limiting mechanic, so that the player gets in danger.
   
6. As for the use of the theme, I feel you used it for the narration and setting, which is fine and welcome, but gameplay-wise, I would have expected it to be taken advantage of, and I do not think this is the case here. Although other people might not ask for it, but I crave originality and I think this is the spirit of this game jam as stated on the official page (and this is even an actual assessment criterion!).

This is some kind of beat ’em all where you play a machine; that’s interesting, but the gameplay needs some tweaking, and it would have been good to have theme-oriented originality, possibly in the ways you defeat the enemies (the idea for defeating umbrella-carriers was a good one).

You can actually build a pyramid of dice and just hold the fort like that 🙂
