Yea like when you are not in space, the controls don't work because of intentional design. The mouse controls are pretty bad ngl they were meant for mobile players but I didn't get enough time to do implement it fully. The wrapping thing is intentional too and yea when you start endless mode you die. You need to respawn in order to start the game in endless mode. Sorry it has no indication that the game is running in endless mode.
Thanks for the feedback!!
