A nice looking game, the enemies look and move good.
It could benefit from more of a map, perhaps some different guns. An upgrade to reload speed would help a lot.
There were also a few bugs, intentional perhaps but reloading takes longer with more bullets. If you reload with half a mag it reloads from 0. You can jump? But there's no real need to. You can also dash and then jump and it will send you flying.
Overall a neat little game. You could add more stuff to give it more gameplay, but for a game-jam game it's good.
