Various Tips
Always use two fingers when tapping in a drumming motion if possible since it will increase the number of taps you can do and give you better chances at success. Scan the area you are in for secret entrances to rooms with loot, different treasure chests, and robots with power ups. Be mindful of the objects close to your enemies like explosive barrels or trees that can fall down and hurt them. Boosts are best to be used in boss fights. Spend your money on upgrades. Watch adverts to double your takings. Keep in mind you can watch an ad when you get a hold on power up to double its effect.
