Hmmm I thought it would be boring but I played it more than I thought I would.
when I saw how the gun rotates I felt that was pretty cool like imagine if it just rotated with your mouse movement freely that would be much worse. made me check if there was anything I'm doing that could benefit from this kind of cogwheel winding type movement, if that is what you'd call it. If often wondered something kinda related about driving games or driving cars in GTA / CP2077 using keyboard and trying to keep a certain (sub-max) speed on the throttle. but I think a CruiseControl™ key would be better for that.
anyway, I struggle to make any suggestions. maybe if the foliage pixel bopped in time with a beat element of the BGM it might seem juicy?
