I love the reflections and colours in the environment, and the gameplay is nice and juicy. Visually it's a little bit cluttered and feels like a mish-mash of assets - e.g. the lava didn't fit, a glowing red floor panel would've fit much better with the rest of the visual style. I also didn't really feel like there was much of a point in moving up - the ground floor was where everything seemed to spawn all the enemies, so I just stayed there.
I noticed the screenshake and the damage numbers, plus a few other little juicy touches that were great! It was also a good implementation of the theme, if a bit boring 😜
