Time does not exist

Hello astronaut, the world needs your help! Time has stopped existing and you need to find 12 pieces of time on this planet. Time does not exist, but you can benefit from that. You are able to undo every action you did, because time does not pass, so why not undo death of your companion, or any wrong move you made. Also you are able to stop enemies from moving. You have to find 12 pieces of time to return time to the normal. You ask why? Because bad guys can do the same thing we can (undo and stop everything), that we can not let happen. Find other astronauts on the planet to help you. This is space, there is no light, so if you find lighthouse it will help.
