Do you prefer searching Crystals in Planet Tabora or gathering Moonstones in Planet Grelbin?
I like finding Crystals at Tabora a lot more than looking for Moonstones at Grelbin. The Crystal searching for me was actually really calming for me and it didn't stress me out too much unlike the Moonstone search. The desert may look confusing and not that appealing at first, but once you know your way of direction through those sandy hills, you'll have no problem what's so ever. Plus I found less things around the surroundings made the gameplay even more fun to play. Like I sometimes say, less is more.
The Moonstone search had a pretty and gorgeous atmosphere, but I found the yeti's chasing and hitting you was really, and I mean REALLY annoying. It was pretty impossible to ignore these guys because they were always on your case and wouldn't leave you alone. The design was visually appealing, but the gameplay felt annoying and frustrating.
