and one annoying thing i found is that after buying all the silver drop chance upgrades and drop amount, it reaches a point where i get more silver than i get bronze so it took me way longer to get the upgrades that costed bronze
Some upgrades are only one level, so it is a feature. I didn't reallize about the token drop. Maybe i should make silver and gold as addtional bonus to bronze token. Thanks for the feedback!
I have the same issue. I think what they meant is that when you buy an upgrade with multiple levels, buying the first level give you the effect of maxing the upgrade, while buying subsequent levels does nothing.
