Cool game! I can see potential in this game. Just if you fixed some more bugs, added more effects, more sound/music, and improve the gameplay. I should make it better. (Rember that playtesting is really helpful)
I believe that is the intended feature, not a bug. You choose a position to teleport with the cursor, then you left click on your mouse and it will teleport you to that position. There should be a prompt above the mana bar that ask you to left-click when using the teleport skill.
