1. rng would indicate that things are dropped randomly if you pay attention its fixed.
2. i agree the game isnt good and that the gold is misleading but i think its this devs version of scoring
and for those having problems with 7 its all about timing not being speedy, and once you get high enough above the first saw there will be platforms to the left and right build on them to beat it if you try to build through the middle youll never beat it.
