Well it seems like an interesting concept and I was definitely interested in seeing where it went considering the setup on the page.  Unfortunately though as you've said below you ended up just going with a basic twin stick shooter, which is alright.

My main problem is with your "chaos" element of turning the screen.  There's literally no indication of what is happening, when it will happen or how to deal with it.  Which obviously leads to a bit of confusion, mainly for me and a few other people that was in the form of thinking it was teleporting.  

Otherwise though, it also completely messes up any orientation in terms of maneuvering around the map, especially since there is no larger map to use to orient yourself around.  Or any major landmarks to remember and base your path off of.  That's obviously assuming there is actually somewhere you want to go, which there isn't much indication on where that would be either.

So overall, a nice base system and a decent tileset for a map, but I definitely feel like the overall design should be a little clearer.  At least something indicating the screen is rotating, or when, along with some better landmarks to orient yourself around I'd say.

Great game designn i enjoyed it, good job!

I don't know where I have to go, the screen keeps rotating and I didn't even realize I could reload my weapon until I was killed, so ... it definitely fits the theme xD

No but for real, it was fun :D

I liked your game's gun mechanics the bounciness of bullets and the level design are also great. Nice efforts.

I like the Graphic, I dont even like the game that have a realistis Graphic so much, but I like pixel art, nice game! 

Great game! I can see the hard work you put into the visuals, the ui, the audio and the game and level design!

But I think there are a couple minor problems:

 -the 90° rotation is very chaotic and each time I totally loose the sense of direction, which is nice, but I think it should be more obvious that a rotation happened (like, turning a bit smoothly or adding some visual effect so that the player knows something happened): I thought at start I was teleported!

 -there are a lot of times I don't know where I have to go 

 -the hidden ennemies are fun and surprising, but there is a moment when there is like 15-20 zombies at the same spot, I (and my computer too) cannot manage this.
