Reasoning due to experience, please.
Um, well, you played it, and its pissing you off. So, nuff said? No? Ok, then read on.
Reasoning; terrible new sprites, copy pasta rooms which graphically are completely unsettling, and jarring form one room to the next, with a terrible system of no rooms, with the same old slow and stupid enemies we've been fighting for 15 years plus. They can't even be bothered to make the colors match up, using the original palettes of their original game. Worthless.
All of this is apparent by simply playing the demo, and or watching any sort of actual gameplay. This could also be seen coming, by intelligent people, since it's first screens were released.
