Wow man, thank you very much for this feedback! Multi-room is actually a great idea, I'll wait for the end of rating to update it with additional rules but that's a neat idea. I actually forgot to mention that students could move in any direction, although I do agree with you it makes diagonal movements more valuable than orthographic ones.
Regarding the Talisman, I was considering adding more chests so that it'd decrease the risks of a player finding it too early, or even replace it by making the Talisman somehow droppable by the Monster if stunned (that'd make sure that both teams are staying close to it).
Alternative activation is also a good idea :)
Regarding the auto-pick-up option for one of the student types (I guess the Wind student, as it is designed to be the one running around carrying the Talisman) is also a neat idea.
About the spells, I hear what you say. At first I wanted players to feel that spells are somehow valuable and should not be used too lightly (and because of the way the spells were designed, the game could get a tad too chaotic if they could be reused at every activation).
Thank you for your time, I do appreciate it. These feedbacks will help me improving on this game and hopefully designing a better one for the next jam!
