Hehe. Glad you liked it. There are legit ways to cross through the barrels, but yeah going around the lines of fire and secure your passage to the objective is a way to go. (I didn't have much time to make the game and make proper level design - Technically the jam was a full week, but in reality I had the time to work on that prototype about 2-2.5 days worth of time.)
Part of not being able to control the camera was to provide you with the element of surprise and ability to quickly adapt as you go, but I understand your frustration.
Again thank you for trying it ! :)
