Really cool idea, and some of the most fun and surprising mechanics I've seen in this jam yet! Took a short while to understand how it worked, and lacked sounds obviously, but I really enjoyed playing this to the end. My favorite moment was when I realized that I had to push in the bullets into my magazine to get the bullets after reloading.
Minor complaint: Restart button was hard to hit when mouse wasn't visible - but it didn't matter since I beat it on the first go and didn't need to restart.
It was so fun trying to improve my strategy on how to manage the floaty UI! You're getting high ratings from me!
