Update 2018.04.02

Thanks for all the launch weekend love! So many videos and streams. Make Sail peaked at over 30k simultaneous viewers on Twitch! We've learned a ton from watching you all play. Today's update is just the start of our work to polish Make Sail until it gleams! * Feature: MUCH easier to start operating a boat while swimming nearby. * Feature: Hold instead of tap R to return to building. Prevents accidental taps. * Feature: Drowning simply warps you back to build. * Feature: Minor input key ui update. * Feature: Flashy pink warp effect. * Fix: Menu visibility error that could happen after drowning. * Fix: Less sinking after traveling large distances. * Fix: Error when active propeller leaves view.
