hmnnn, the animation is okay, tho, the protagonist doesnt seems to have much effort into killing goons, also, every room, just one of those going into a room and killing everyone kind of thing, the character doesnt act reasonably like not taking cover and shooting on the move.
other than those, you did put effort into making this, and you're skills are above average, plus I like the twist at the end, so yeah, i'll give you 4.5/5 stars
