I unlocked and upgraded everything in preview and didn't even reached 50 planets, now this one could not load my previous save and have to start from 0, ummm no thank you i'll pass :-/
Few suggestions: In areal seems there are a lot of turtle which can give lots of VISCERA but there are no way to kill them because we cannot drill up, so make them blow-able with dynamite at least. Also it is almost impossible to find corals, so make them visible on the map either with optics or radar, also even though upgraded optics says that it will show living organisms it does not. Anyway i already upgraded 70% of everything now just trying to get every single viscera, chitin, and pearl i could find and there are only 2-3 bugs in entire planet -.-
Gahhh need to have some saves, i've completed first 6 hard levels like 5 times and then got to leave computer close browser etc. and every time i come back nothing saved and i am back to lvl 1 -.-
No for the music, but the upgrades are good idea.. i will put them maybe in a future version.. Thanks to the people who played.
