Hi there, I'm so glad you have been enjoying the game. In the current itch.io version I believe this is still the case. Gold should be increasing much faster in levels above 300 than it was previously. This is base gold of course so the various multipliers will still be your go to for gold gains. In terms of crystals the higher exponential gain is active in the current itch.io version but my main site (which is easier to update and so gets updates first) has a reworked crystal system where crystal gain has been slowed overall but the multiplier from crystal spores has instead been heavily buffed. I highly recommend playing on the base site, the new button inside of the itch.io version should be able to port your save to the main site. I tend to wait until many updates have happened before accumulating them inside of a single larger patch for itch.io, totally up to you though thank you for being a loyal player and I hope you continue to enjoy it! All of that being said I do also want to support my community on itch.io so I will package an update for the latest version soon!
