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), but the energy will be "divided" into several potions - one for each stage, not just one potion that gives all energy at once.

Upgrade
The upgrade consists of 30 levels (20 at first season, version 1.0.5), and each costs will be 500 coins increased than 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.
