This was wonderful - really fun to play, with a diverse roster of enemies - the speedy ghosts are bastards in the best possible way, and the mortar ghost is just a delight! Managed to survive on my second attempt once I'd figured things out :)
I love the attention to detail that's gone into ensuring that all important information is communicated clearly to the player, with the little flash when your ability recharges and the circles used to indicate your sphere of influence. It made gameplay feel really intuitive
Also, just wanted to ask - what's the font you're using? It's gorgeous :)
