So why would I play this over wolfenstein which already exists? I'm sorry but you probably took a base level engine and kind of tweaked it. The sprites are overly large, the overall feel is that taken directly out of a made for play engine, all thats been added is "chibi" sprites. This really doesnt feel exceptional or necessary in any way. Thats my problem. Nothing feels better than what has already been done.
To compare: Iron main (ion maiden) Is an evolution of Duke Nukem but similiar style. This is more like a chibi wolfenstein but you've not evolved or done anything. Instead you just pallet swapped and tweaked the sprits and levels. Yeah if the level design was exceptional that would change things but what you've displayed is that you are capable of pallet swapping, not environmental design not in fact change things, you've shown that you in fact understand the basic components of the game engine design itself to make it functional.
There's a lot to learn and I want to improve myself and others but that's the problem here, this is a basic one to one. You've shown you can turn something into something else. Make it unique and do something more than. This is basically "chibi wolfenstein" Without any value.
