So I am 6 hours in and already wish I could hit restore on what has been a pretty fun game.
Below are my 3 main mistakes I urge you to avoid
1. Use the link from UplandPublish0x competition, it doubles you starting UPX coins, you would be silly not to
2. Watch the tutorial, it's quick, it's colorful and it helps, I skipped and regretted it, had to go back, seriously it takes 1 min
3. You start off being able to buy discounted properties, but only afford about 3. Before you buy go into collections, these work a bit like monopoly, you get a boost to earning and some extra UPX for unlocking them. Have a look for a hard one and try to do that, like buy three properties on the same street or an certain part of town. I just bought 3 random ones so had to settle for the beginning collection which only boosts one property
P.s Also if you see a Piñata click it like crazy it's drops a lot of UPX
