I'm at 18 hours in, but I got bored with it 8 hours ago. I have a little more to unlock, and most of the achievements yet to unlock, but I feel I've seen everything the game has to offer. At this point it's just the same thing over and over again, with very few meaningful gameplay decisions. I'm done.

I really wanted to like this. I think I gave it a fair shot by playing it for a couple hours. I have nothing positive to say about it.

I like it. The parkour is fun. The combat is fun, and the graphics are beautiful.

This might be worth it just for Dungeons and Diagrams alone.

It is what you make of it.
There are more than one ways to approach this game,

You can brute force every puzzle with zero regard to cost, area, or time (the in-game scoring mechanisms, where lower is better). Anyone can play this way but I can't imagine anyone getting real enjoyment from this.

Or you can obsess and try to make every contraption as efficient as possible, using the smallest footprint possible. Some people really like doing this, but this style of play isn't for me.

The enjoyment I got from this game is somewhere in the middle. I didn't worry about trying to score on the top of the leaderboards of every parameter. I just like building stuff.
What I like the most is witnessing a ballet of moving parts and seeing everything come together.

Imagine a rube goldberg machine. If a rube goldberg only has a few moving parts and lasts a few seconds, it won't be that interesting.
But if a rube goldberg has more moving parts and includes some impressive-looking tricky maneuvers, it's really exciting to watch. That's Kaizen for me.

Don't drive drunk under any circumstances! Even if the hitchhiker in your passenger seat complements you on your driving and says you'll be fine. It's not worth it.

It's really kind of dumb. I regret this purchase.

I could see myself getting sick of this kinda soon, but it's really addictive.
