If you have coins available, start with a Full Attack boost to deal massive first damage to your enemy. Counterattack is also a good option if you have the coins to spend. Do not hit any obstacles because they will drain your health. Be patient and gather red coins until have a maximum strike that will cause a critical hit. Watch your health and get the green coins when necessary. Do a weak attack as soon as possible, in case the enemy has the Counterattack boost purchased.
Changing lanes
You can change lanes while jumping. This will be a required strategy after Day 3.
Coins
Play Collect mode first, before the competitive games in Battle mode, to learn the game and earn coins. You may have a choice during a run to collect a box of coins or pairs of coins. Always go for the coins, as you will get more. One box gives you five coins, while the pairs will give you a lot more.
Power-ups
The boxes with a question marks are power-ups. Always try to collect them when possible. The one that doubles the coins you gather is particularly useful.
Upgrades
Get the Bug Doubler first, then the Extra Health and Extra Attack (especially when planning on playing competitive games). After those, work on Defense Shield, Magnet , Invisibility and Rage.
