This is a very good idea and entry! I would love enemy actions to be faster though, it takes a while for them to prepare, hit and, as I understand, I cannot do anything to stop it.
I got lost on the third level (exit was blocked by webs and I couldn't understand what to do).
Teleport was a strange one to use, it seemed that it only prevents one attack, which is kind of pointless, since its basically you skip a turn and enemy skipts a turn. And blizzard seemed to be reduntant, since either enemy die from one fireball, or two. But they still would die to two blizzards either way. Arachnophobia helped to kill slimes in one turn though. Maybe other levels would give blizzard a chance - idk.
Everything was good otherwise! Liked how it sounds and how it looks!
