Energy Boost

Energy Upgrade is a permanent upgrade that increases the energy potion at the end of each stage. The energy potion are very useful for running in long distances. The upgrade is stacked with any cookie (e.g. Brave Cookie Lv. 8 has 100 energy, with Energy Upgrade Lv. 30 the cookie has a total of 250 energy).

Upgrade
The upgrade consists of 40 levels. Originally it has only 20 levels at first season and 30 levels at the second season. Each upgrade costs will be 500~600 coins in increment from the previous upgrade. It gives cookies an extra 5 energy as a bonus, then increases by 5 for each upgrade. When upgraded to Level 15, it allows the player to buy Knight Cookie with coin.

This is a high priority for all amateurs. It is highly recommended to upgrade to level 20 at the minimum for each player.
