I loved this! The mechanics were so tight, which is impressive for a gamejam game - particularly the risk vs. reward of staying out of cover to improve accuracy and moving between cover to divert enemy aim!
I would have liked an ammo/reload system to keep the pressure up. But I loved how you added a combo system too which adds replayability/speedrun potential. I wasn't able to finish it, but I'll be coming back to this one!
