Today I am officially done. It has been a month since we have even heard from the devs. I am no longer willing to check in and buy my 1 oxy bar anymore. Although many committed players have lowered their ratings and complained, nothing has been done. Therefore I am taking the last step available to me and will no longer play. I hope this motivates some change and will benefit the rest of the loyal players.
Banks seem a little overvalued. I'm a decent way through the game (nonillions of shares) and they're really the only thing worth having. Unless upgrades directly or indirectly affect the banks, it doesn't seem worth it.
Devs aren't going to get the message till people stop playing. If you're looking for a good idle game that doesn't have big gaps or walls, check out Holyday City. It's what this game used to be.
