Thanl you for the feedback, I am working in a new build with a bunch of balance modifications. Lot of people told me about the difficulty factor, it was too high.

I liked difficulty when understood more about others spells and how I can combine then. But at start I was confused.
I didn't understand at start that ice spykes are at touch distance and how much I need attack enemy to kill them and how manage to do it without dying.
At the end I came up with strategy: set totems at the end of the line - when enemy near it: use ice spyked ones and after recharge second time to kill.
Mostly difficulty was to figure out strategy, but after 1 level everything was better, I have had strtegy + new spell.
Cool, I added a "telegraph" mode to certain spells, including Ice Spikes, so the players know the range. I think the error is in the first level, it too much punishing to the player. I changed number related to energy and player hp as well.
Again, thank you for the feedback, I really appreciate you took the time to pass the first level. Some people just gave up.
