when game is working its quite nice but.... alot of the time i get issues where game just totally freaks out.
had issue with learning tab as had to click set all to 0 so i could actually start using it as had some sort of bug where it didn't want to use any of the energy i got.
then on summoning instantly had all summons die when went to start have a miner as instantly burned through all my energy.
when it killed my summons instantly game stopped all progress so had to refresh page to force it back to working
