things i need in pokopia:
A better way to dig. in particular; digging out bigger portions out faster. Graveler is good for small, straightforward, sections. but digging out bigger chunks out (with accuracy, and especially downward) is a huge pain ass.
A separate “god mode” (or i guess “Arceus mode” in this case) where you can just build whatever without worrying about materials and whatnot. Obviously separate from your main file.
Being able to dismantle your own building constructions and build them somewhere else. in other words, being able to use the “dismantle” set on your own buildings.
i think that’s about it really, as far as mechanics go.
