The no reset skill thing actually encouraged me to play through the game several times with each skill tree! What at first I thought was bad is now good!
Very good! It is very much like World of Warcraft and you can tell the creator borrowed some aspects. 5/5 I want to see more flash RPG's made like this!
The routine for the snake boss is... where ever the nice closed mouth snake goes the open mouth will not. So go to the middle of the place and wait till you see the closed mouth one go by and stand there. Rinse and Repeat.
