This Is a well known bug but just in case you did not know there is a bug where some of the major Keybind's are just not set. I Believe this is just a unity export issue but here is how to fix it.
------------------------------------------------------------------------------
1 - Pause The Game While In The Editor. Your Screen should look like the screenshot below
2 - In The top right corner hit the button that says "Level Editor & Game Keybindings
3 - Hit The "Restore Defaults" button
------------------------------------------------------------------------------
Then you are done all key's "should" be bound

ALL OF THE STUFF BELOW IS OUTDATED DUE TO THIS BEING PATCHED THOUGH I AM KEEPING IT JUST IN CASE SOME ONE DOWN PATCHES TO 2.0.1

One Time Event Obstacles Get Deleted Once Triggered In The Quick Test
------------------------------------------------------------------------------
1 - Before playtest
2 - During playtest

3 - After playtest

------------------------------------------------------------------------------
This Bug Sucks So Bad It Make's Playtesting A Nightmare.

The Only Way To Fix This Is To Replace The Obstacles Because Even If You Quit Out And Reload They Will Not Reappear.

ALL OF THIS HAS BEEN FIXED AS OF 2.0.4

Player's Shadow Does Not Despawn
------------------------------------------------------------------------------
1 - This happens when you are doing a quick playtest via hitting F1. all you need to do is hit F1 once than hit it again. Below is quick playtest screenshot

2 - Below is editor screenshot

------------------------------------------------------------------------------
This Does Not Effect Anything But Its Something

ALL OF THE STUFF BELOW IS OUTDATED DUE TO THIS BEING PATCHED THOUGH I AM KEEPING IT JUST IN CASE SOME ONE DOWN PATCHES TO 2.0.2


I Have Tried To Recreate This And Before The Update It Did It Every Time But Now It Seems To Be "Gone" If You Have It In the Latest Version Please Comment.

Huge Part's Of Levels Just Vanish Without Any Way To Recover Them
------------------------------------------------------------------------------

------------------------------------------------------------------------------
This Happens When You Do A Full Playtest And Hit ESC Then Hit Restart Level But This Can Sometimes Happen After Saving And Quitting. I Also Had This Happen When I Exited A Quick Playtest.

THIS IS THE NUMBER ONE BUG THAT NEEDS TO GET PATCHED
