Thanks for playing and such detailed feedback
I really need help creating key board controls, I was mostly a console gamer before i stared making games.
here is how I play
the birds (crows) can't be killed by design and they remove one vanquish point if they hit you .
also the player has no health points his life is on a timer.
At first you need to stay at the bottom avoid the Undead General ( blue Zombie ) and kill the 2 Undead (red zombies) you must avoid the crows , you will get 2 vanquish points , that is all you get first round then upgrade Speed ,then you will be able to kill 3 the next time, It is a bit of a grind at first. next upgrade strength by 1 and you will be able to defeat the Undead general. then getting the vanquish points become really easy, when you get the double jump you can get to the top platforms where Antoinette's statue adds time to your timer. then grind until you get 50 vanquish points and the HELL CAT will appear, defeat the hell cat and you beat the game.
my fastest play trough is about 12 minutes (but I must have played it at least 100 times looking for bugs )
hope this helps and you give it another go!
I need to add coyote time and a jump buffer to the player controller, have a look at the source if you get a chance.
