A lot of upgrades are pointless.
I don't have anythinng wrong against walled upgraded as long as they bring some what of value, but I feel like most of the time I'm just waiting to get income, wasting it in something that does nothing nor fasten my econ, all of that to just upgrade 1 thing that slowly fasten it. imo need major balancing in the gameplay itself, otherwise it's ann ok tier incremental, graphics and UX are the thing that carry the game, but the whole gameplay loop & UI are imo really really bad, solid 4/10.
