That was really impressive ! the game played like "Hotline Miami" combined with the guns of older classics like "Metal Slug" and "Contra". It seriously gave me some nostalgia playing those games.
The same can be said about the simple but effective use of sound design and music composition. It really ties everything together.
I also liked the balance of each guns, nothing is too overpowered, but as a player you'll naturally favor one type of playstyle over the other. I personally liked the shotgun over the sniper as I like blasting more than aiming :P
(the bazooka on the clump of enemies is just *chef's kiss*)
Really hope this game get's more ratings, as it really is a gem.
Congrats on completing the jam !
