The resolution was absolutely terrible. The screencaps shown are vastly different from what I experienced, and not only did it cause a lot of problems, it muddled the obvious fact that the weapons you're using are clear ripoffs of Samus's Beam weapon in Metroid Prime Hunters.
The boss fight itself is made cheap with seemingly hilariously easy maneuvering made difficult with the lack of proper visual aid from the up-scaling, making what should be a simple task into a colossal nightmare. To make things worse the light generation coming out of the pixelated lava/weapons only serve to further obfuscate and annoy my as I attempt to work between the mediocre mouse look (which was slow even with max settings) and the collision detection that truth be told I didn't have any confidence in due to the fact that my screen looked like a game boy being displayed on one of those blimp monitors.
It's fine if you want retro/lowres. It's fine if you want inspiration. This is neither.
