Thanks for taking the time and comment :)
I thought it was a goofy concept that really needed to be executed.
It was also my first time playing around with 2.5D, and now that the JAM is over I don't know how I'm going to go back to plain top-down 2D hahaha. The balance is definitely the biggest flaw at the time, some perks looks amazing but are actually not good in the end just like the fertile upgrade which may be the worst of all.
To progress, the best is to optimize damage to kill villagers quicker (holy cut, holy pointy) and still stack upgrades to zone out enemies (holy cow, holy arrow). In the end the perks upgrading mere stats are not much of a change, definitely need to tweak that up.
