That's... it, I guess
Like, it's neat but it's also kinda mediocre and they basically focused so much on combat that the /game/ part of it is just kinda tacked on top.
There is some basic scripting and triggers and what not, but they are at best persist only within a single level and have no sign of existence the moment you get to the exit. Though you can cheat and make a bunch of branching level transitions to fix that, which someone tried, but it's uh. Well it's not that good I feel like? Though now it does remind me of older games that just have "levels" and no single fixed world.
Actually now that I think of it, "bunch of separate levels" describes a lot of games, but they try their best not to flaunt it too much, and a single "level" can be quite full of stuff to look at and explore. Which is not the case with Overgrowth where it's "punch these 4 rabbits to death" and that's it. And then everything jumps to another scene...
Though, this is definitely a rare game where you look at a distance feeling hill and go "damn that's big" and then you can /get to it/ and climb it. Or well, sometimes that can happen? IDK
Just kinda rambling thoughts with no solid conclusion after I downloaded this game once again, played it some, and put it away for next year or two until I get bored and take a look at it again.
