Ok so -> super super super cool idea. Having 30 ghost running around and each causing 1 HP of damage to relevant enemies or solving puzzles is very cool.
I did struggle a bit with the controls. I think the enemies were very quick to respond and I didn't really have time to get there in time. So out of 5 loops I would only get 1 hit in.
But then the payoff is that you build up this little army that does a bunch of work for you. It looks cool and chaotic :-)
