Keep Craft - Idle Civilization

I like the game, it’s enjoyable for the most part, a little bit grindy but not too bad (so far at least) but I’ve run into a bug where I can’t invest knowledge anymore. The button to invest is just greyed out. I’ve tried deleting it and reinstalling, didn’t fix. Please fix?

You hit a point where you’re spending several hundreds of blocks for minimal storage upgrades which are needed to progress. It takes literal days to gather enough resources after not even that much play time. It’s fun for the first few hours. It won’t be a game you’ll play very long.

Honestly didn’t expect much with this title, but it be prestiged three times now and it’s still pretty fun. This is a resource collector kinda game with some gambling (heads or tails, picking 5 cards out of like 40 for coin values) aspects and it honestly worth a try
