There is a new build of the game on the page so I'd be curious if it addresses some of your biggest concerns from the jam. Mainly overhauled the graphics and made it so the "hip fire" aim doesn't scroll vary far and you have an optional ADS for the times you do want to aim further away. There are some minor small things as well, but the big thing still not added is more depth in enemies and weapon upgrades, but there are now melee weapons and grenades.
