I must start with saying; the game looks gorgeous. No seriously, it's beautiful, you really outdid yourself on that front
I do have a good few problems with the game nevertheless.
The difficulty is bonkers; it's frustrating, and the amount of damage enemies do forces the player to play more defensively and slowly; an obviously stark contrast to what you were going for.
I understand what you were trying to go for and that similar games are as such, but for a game jam it is simply not sufficient. The enemy hitboxes were also rather small.
When you get the hang of the game though it's an absolute blast; the movement mechanics are very intuitive and pave great potential for interesting level design. My only problem with it is that you really should just be running by default; in such a fast game, I always forget to run, and it's annoying to have to hold down the shift key whenever I want to.
Some levels I had no idea where I was going to be honest, though that may just be a result of my own mistakes.
Overall, it's extremely polished, and the shooting and movement mechanics are insanely fun, though it is locked behind an exceedingly high skill gap, not sufficient for a game jam.
