Hey, yee I barely made under the deadline so many aspects of the game are not explained. So abilities are automated, like shield will automatically activate once you were hit. About health, here I actually haven't fixed this bug. I will fix them in the near future
And to make past huge gap. If you noticed the red marked turret's knockback is strong enough to get you to another side. Just get hit by it, there is a platform facing the wall. This wall will stop you just over another platform that will catch you
