I guess I killed everyone. The movement is really slippery, but it is kind of amusing that way. I find it weird that there's a delay before you can jump again, but there's no reason to jump in this game as far as I can tell so it's not a big deal I guess. I personally didn't find a problem with the sensitivity, but I usually have to set my sensitivity higher when playing games so I suspect I'm in the minority.
The game could probably benefit from having more of an indicator of when you're spraying, and I was also hoping for a bit more visually when the villagers were sprayed. Playing the spray sound even when not spraying something that can be sprayed would make more sense, and having a visual indicator would help as well. The villagers could also maybe turn a darker color when they get sprayed to indicate they're wait now.
I also think the spray bottle should be in a more obvious spot or the player should just start with it, as I didn't notice it when I first started and restarted the game since I thought it was bugged.
The concept is very funny, but there just needs to be a reason to kill everyone.
