the idea is amazing, the game is very fun, and i hope this game gets developed further.
one problem is that the way permanent buffs are implemented leads to strategies that optimize the fun out, in my second round i continuously +1/+1'ed a ent, i usually intentionally slowed the game down to +1/+1 it further and avoided victory, i think a good solution for the problem would be permanent buffs being larger but triggering under specific somewhat hard to trigger conditions so that they give you a small side quest during the round instead of just being on a timer (as a timer giving buffs always makes you want avoid victory for as long as possible).
