Yeah, this is a good concept with broken mechanics.
Starting with the use of the gun, why?, second, the reloading time just takes too long, parry mechanic are somewhat useful with aya, but I still don't understand why youhad to add immortal faeries, I almost thought it was the final fight just for that.
And never really used teleport because it hardly explains when can it be used, sometimes works, sometimes don't. I might suggest an infinite double jump, because it is just not enogh in some places, believe me, it doesn't make it any easier, but reaching enemies and keys is just a pain when you don't have an idea that you had to touch them, I thought I had to shoot them (?
Music was a curious choice, I like it, but it doesn't seem to fit, but I like it (?
