the abd thing is I couldnt even offer you any suggestion how to fix this as just giving you tons and tons of resources would allow the players to jsut max out everything early on, before even "advancing" to further area. which would be kind of pointless.You could limit the current max level that a thing can be ugpraded to based on the current advancement level. but no idea wether that is feasable tio implement nor if it is a good idea, since it basically wont allow ou tog et a bit overpwoered before walzing through the enxt wve if you get my gist. and being overpowered can sometimes be pretty funny if you dont overdo it.
