This game's aesthetic is exceptional! Art and animations are one thing (that being very pleasing and polished), but I love that you went the extra mile to design the game around the camera perspective you choose. It really made the whole experience more memorable.
I also love the details of having to manually load individual bullets. I did have an issue where clicking "Load" caused me to fire a bullet (in one instance, my last bullet, the very one I had loaded haha), but I'm glad the feature exists. Though the enemies did find themselves unable to reach me, so I couldn't win, but I also couldn't die or game over.
Great game! I can see a lot of work went into this. I'd be impressed if this was a team project, but the fact that you made it solo makes it that much more amazing. Congrats!
