In my opinion, this is very easy to get level skills that will spend mana LOTS , it is very disproportionate , this is more an observation than an opinion .
Hi, I actually made the mana costs high so that you have to decide between what to upgrade with your limited mana pool. You may have realized in late game that it is not always worth it to upgrade a skill even if you have the EXP to do so - which is why I put a level down button, so you can downgrade skills and strategize/experiment with the different skill levels to allow you to see what works best. I understand the mana mechanic isn't very clear so sorry about the confusion. I'm still working on making it better/more interesting. Thanks for the observation!
