So there is a few things to note.
One its not apparent of what to do in the game and should really have some kind of tutorial before the game starts.
Two i don't like being forced into full screen so I would suggest u fix that so u don't and if its a UI issue then fix that in engine so ur UI scales correctly especially in windowed mode.
Three I was in the game for a few seconds and I died from the sun which is too fast for a new player to the game.
