like other people have said, earn more money from being bigger. it does seem to happen but its not super noticeable and it seems to plateau at like lv 2 or 3 of one aspect. should be a little more significant at the higher levels
higher levels in general. max of 4 for each makes the game super super short. kinda the whole point of the game is to grow so why make such a short limit? i figure higher levels are coming down the line, but if it were me, that would be the number one priority
a change to how the potions work. it should be way more clear how many you need to level up. so we don't waste money on a small potion that never makes a dent. or a big potion when a couple smalls would have done the job. all we really need is a number out of 10 or 100 of how far we are to the next level.
