Well like i said, didn't mean to make it quite as hard, so don't worry it's not you, the game is just not well balanced :p
Glad you liked the atmosphere, mechanics and visuals though ^^
I should have given at least 1 mana or 2 from the get go to allow players to summon maybe a fire book of their own and maybe have a few more chests lying around levels.
Thanks for giving my game a shot and taking the time to give some feedback :)
