I liked the tutorial sequence, it has a nice amount of humor in it. The music is super cool (I think I heard a Megalovania riff at 1:49 lol).
The gameplay is very complicated, and the game would benefit a lot from introducing features incrementally, one by one. I also couldn't figure out how to refuel, I unlocked all 3 slots, but I only had two weapons, so the game equipped the gripper with my gun, which prevented me from shooting :
Overall, the visuals and especially audio are very nice, but gameplay is overcomplicated and convoluted. A simplification and a more incremental tutorial could be very helpful!
