Grind out coins on
Level 1-3, it has easy enemies and not a lot of environmental threats! Feel free to get to Level 4-4 and backtrack to Level 1-3 with all your upgrades.
If you get the "
Max Coin Loss" upgrade it can help while grinding as it will limit the loss if you manage to get hit during your run.
I also advise banking your coins after you get hit for the first time to play it safe :P
