Thank you very much for all your feedback!
You're right, there have been a few people to mention holding the LMB would make it a bit easier on the wrists, this is something we will consider for future games :)
And yeah the fireball sound crackles a bit when it gets spammed, we would've tried fixing this but sadly we ran out of time in the end.
We both decided not to put a cooldown on the teleport because we thought it might be a bit too difficult without being able to teleport constantly. That and it felt more fun teleporting around kiting the skeletons :D!
Thanks again for your kind comments it really means a lot to us!
