Really enjoyed this game. Mission 3 was a bear, those little green enemies are real bastards. Not sure if it was intentional, but you've definitely got all bullets on the same collision layer, which makes for some interesting emergent gameplay. It's a shame the default volume of the music is so low compared to the sfx, I didn't realize it was there until I explored the settings menu! Overall a nice twist on the genre (specifically the reload mechanic), and a great entry.
