I really liked the upgrade mechanism; it was great to be able to enhance everything—from specific weapon stats and passive abilities to movement mechanics like jumping.
However, I couldn't quite tell if the enemies had become stronger or if my character had actually gotten weaker. Using a "scratch card" (upgrade item) sometimes left me feeling like I’d ended up in a worse position.
Regarding the reload animation, rotating the muzzle by about 90 degrees would likely make the reloading action much more visible.
Also, the ammo UI isn't very easy to notice; it would look much better if you added a "World Space" canvas near the gun—perhaps positioned toward the rear sight—to display the current ammo count.
Still, you’ve clearly put a lot of hard work into this! It was easy to pick up and quite fun to play.
Would you mind providing some feedback on my COUNTIST as well? I’m currently in the polishing phase, and feedback would be incredibly valuable.
