I've been enjoying it so far. Played it all weekend. There's almost always a stockpile of needed pieces lying around anywhere the game expects you to do something, and if you're always collecting more Zonai Device capsules whenever you see a dispenser, you'll always have a surplus of gadgets to build with when you feel like it.

Once you get the autobuild ability, you can even spend a currency to generate the parts you're missing if it comes to that.
