how I got medium badge: follow some of other people's advises. focus the 3 main upgrades which would be Drill strenght, hull, and fuel tank. I only put like 1-2 upgrades on steering wheel to save money. save the 2500 depth trophy for last day. when you have 9-10 days left you should have the 3 main upgraded, and possibly working on maxing nitro, mole, and radar too. you should have a nitro upgrade though about 1/3 way of upgrading the 3, so you can have extra money and depth for extra cash. I spent one day to get the coins trophy, then one day for both treasure chest and sapphire, refresh if you didnt get it before the animation about fuel out/pressure. then I think i spent like 2-3 days on the ruby/diamond/big diamond trophy. if you refresh enough like me you could get ruby/diamond in one day. then you should have like 2-3 days extra to farm big diamond. aim for 20-31 per day, refresh if it is low. count if you need to.
I accidentally edit an older level from the Create Tab instead of from the published map... so now i have two maps with same name but one with lower kb size. can i have an option to delete the other one plz
