Hey man, cool concept, leave you some overview if you're interested.
3D + Pixel art goes really well with those lighting effects and particles, the downsized resolution sticks all together nicely. The movement feels good and fast paced. Love the trippy moving ambient (shader picking up vertices?) and the particles give the juice it needs.
Enemies could have anticipation animations to figure out when will they shoot, although lighting does the trick sometimes.
Simple path-finding would have been nice for enemies to not stick on places.
Overall interesting experience, very unique aesthetically. I also made my own entry if you're interested in checking it out.
