Overall this game feels way clunkier and less intuitive to play that the original grounded.
I think the biggest thing is not auto resuming sprint after stopping or melee. The sprint mechanics of Grounded 1 were some of the best mechanics in any game ever, please go back to that.
Also, the omni tool should be an actual tool that can be equipped. When trying to chop down grass, weeds, or bust rocks, any bit of inaccuracy throws it off. Hitting things in grounded 1 with the appropriate tool was much smoother than this new system. An equippable omni-tool would solve this perfectly.
