This is a cube achievement based game. Your goal is to try to unlock all achievements mostly doing so by surviving for as long as you can. The main goal is to try to survive for 999 seconds. Do you think you have what it takes to unlock all achievements and become the ultimate Cube Survivalist!!
PS: The game file is a jar file so you just need java to be installed. It works on windows 7/10. Since it is a java it probably works on other operating systems but since I haven't tested it I wont say for sure.
