Love the style, gives a really nice atmosphere. But I think the different bullet types deserve better treatment, it is intuitively difficult to figure out what everything does. Or maybe I am just unfamiliar with the genre and am opinionated about UIs. Styling the vending machine as an actual vending machine might have been interesting.
Your description says you are aware of bugs etc. etc. so I suppose you thought of these points already.

Thanks for playing and the feedback. Could definitely have done better on the visual of different bullets taking effects. That's a whole UI system I gave up in the end due to time limits, but turns out to be still quite essential T_T I did expect that the game rules might rely heavily on visual communication but it still exceeds way too much. Anyway thanks again!
