You cant stack up energy, but...

300 energies will literally get you through about 15 clicks worth dialogue..the story line is good but you cant stack energy (as in open the app collect 300 energy then close it out and do the same thing the next day. Youd still only have 300 that you can use) Other than that story line is good..but it could provide more energy or just the ability to do that for up to 1200 energy at the least!
