skill builds would be great so you can switch between builds whenever you want.. it could cost a bit like.. a billion pixels? like an idle and a none idle builds.. an idle one would focus on rewards while the active one on power that could be good.
The achievement thing.. why it is just the same for every level? it takes the fun of most levels specially to a perfectionist like me... I liked the first one but those achievements..
If you can't find all the seed parts they are not in the totem the ice are have 2 seed parts one of them is well hidden and in the first dungeon there is an extra seed once you learn to swim hope I helped.
paratroopah have a bug when you complete a level it finished with the troopers and don't cout to the stars which means it is not worth upgrading till they explode on impact
