Having recently gotten a sunburn, this rang pretty true. Nice game jam submition!
One note I kept bumping into was the need to push E to interact. Since I was using the mouse to look around, it would have been nice to just use a mouse click for those interactions.
I would have liked to maybe see a second level with a different type of umbrella or more people to manage between. Understanding how much time I had before getting the scoreboard might be good, too; on that first run, I burnt everyone and then just waited for something, but I didn't know what.
Hey, nice game jam submission. And yeah, let's all use sunscreen.
