A straight-forward interpretation of the theme with an excellent execution. All the feedback are there and it feels very polished. However, I think forcing players to sacrifice may put them off, especially if your deals don't cover the expectation of players. For example, I want less enemies for lower running speed, and that is not an option. Tradition top-down shooter makes the player feel powerful and players are used to that way. I think some of the deals you offer make the player feel less powerful in general (one that introduces a new type of enemy), and winning the round doesn't feel as rewarding because now I have to make a sacrifice as the game tells me so. I personally like the upgrade in bullet size, and the sacrifice is worth it. Regardless of my nitpicking feedback, you two definitely did a wonderful job this jam. Good luck with the results!
