Downloaded game the first day it was available and have been playing faithfully everyday, these are the things my friends and I have noticed need improvement. I'm sure this list will be updated as gameplay progresses.
*Having the ability to place a angled floor piece and then build a square floor piece directly off it following that angle would be amazing.
*Ability to affix pallets of inventory (planks and stems) to zip lines.
*Rank up buggy (damage, capacity, stamina)
*Permanently keep plants from growing through buildings.
*Damaged enemies don't regain full health upon player death.
*Ability for buggy to revive you.
*Don't show molars you've already collected on the map. What's the point!?
