I like the graphics, the style feels sort of...metallic, I guess. The sound effects when you hit something add to that feel. They're pretty satisfying. The style really gives you a sense of a different world, like your own little strange place. Also, props to you for having voice acting. It's pretty good too! One problem is that sometimes the characters don't have a break between lines, so the moment one finishes, the other starts. Occasionally they even overlap a bit. The main "campaign" is a nice way to pass a bit of time, while endless mode is nice because it's longer, but could be a bit more difficult. The foxes don't show up very often so you're mostly facing frogs and squirrels, which can get kind of boring. Even the squirrels take a while to show up. Maybe increase the challenge and ramp up the pace a bit. Considering the movement speed making the shots cursor-guided was a good idea. There's one thing you should tweak. The enemies shouldn't be able to hit you when you shoot them. So squirrels shouldn't be able to shoot, and others shouldn't directly hit you, though it might actually be better if the squirrels can still hit you to add some challenge since they usually miss anyways. Maybe make their homing better, at least in endless mode. Maybe also add some medals and leaderboards as extra reward and incentive. One thing that annoys me is that in endless mode, you don't move your hand around to shoot. It's a small detail, but it just annoys me as an inconsistency. Overall, it's a simple but pretty fun game that might need more challenge and some slight tweaks. I quite like the style.
