I played this, but didn't really like it. First off, the random buildings and villages are nice, but it can cause stupid difficulty spikes and usually it's simply not worth exploring them. On one level 2 planet, I found some sort of Aztec temple with enemies that had sniper laser rifles that literally did 100 damage in one hit. After a bunch of digging around them and doing weird stuff, I finally managed to get past them, climb to the top of it and my reward was absolutely nothing. On the other hand, right next to the temple, easily accessible was a chest containing the double jump tech. Also, while randomly generated enemies seem cool and all, there's basically three types: the guys that do nothing unless you attack them, the guys that shoot you and the guys that run at you. They do look different though, which is nice. Then I encountered some miniboss and it dropped a legendary bubble sword thing that looked awesome, but actually was far worse than my "crappy hammer". Ores other than copper and the occasional iron seem to be very rare or only found undergroud, but digging underground seems to get you pretty much nothing. Because of the leveling enemies, it doesn't really feel like you are getting stronger either. You can pretty much one or two-shot enemies or they one/two-shot you. So honestly, I much prefer Terraria for now.
