I think I did okay!
There was a point where I thought "I'll never run out of bullets now" and then... well anyway, great job!
I like the mechanic of reloading by going onto the tiles, and how once you've used one there's an indicator of where the next one will spawn into place. And how you can't simply camp one that's currently recharging.
Sounds are nice, especially there's a nice audio-cue when you try to fire while empty.
All the art is visually pleasing, everything is clear and color coded.
