Crazy how many plays this got when there's definitely games out there which deserve it more
A lot of people have already said a lot of things so other than that the core loop just isn't interesting, I guess i'll say that the multi-harvest upgrade is pointless. If you're holding down click (which is still the easiest way to do it), you'll stop moving as soon as you come within range of one tree and just never hit a second.
Hitboxes are janky enough that it's not worth trying to always hit a second tree, you'll just be slowing yourself down doing so (and needing significantly more attention for that slower speed!)
