Thanks for checking it out!
I still have a lot of work ahead of me on the last day of the jam, among other typing up detailed instructions. I uploaded an unfinished version mostly to get some feedback from the Pistol Whip community, as they're already familiar with the game this is based on.
I won't be adding more enemies in this map, as it's a map from the original game and it's very iconic, including the perhaps slow start, but I'm hoping to manage to build one or two other maps by the end of the day that hopefully won't suffer from this particular issue.
As for the game being difficult, yeah, that stems from trying to be true to the original (dodging shots is waaay easier when you have 6 degrees of freedom of movement). I was planning recommending the "bulletproof" modifier for new players, but based on your comment I'm thinking it might actually be best to have it enabled by default. Getting hit carries a hefty score penalty, so it's not like invulnerability trivialises gameplay, it just makes it less frustrating.
