The game has 30 levels.
There are six boss battle levels, and some strange mechanic levels and story levels.
You can choose 3 combinations of 5 active skill parts and 4 passive skill parts to complete the battle before each level. When passive parts reach a certain number, new features will be generated.
Active accessories include stealth, shields, rapid fire, bombs, and mines.
Passive components include increased health cap, increased damage, increased movement speed, and decreased active skill cooldown.
There is a certain storyline and a written description of the stream of consciousness (the memory fragments obtained after each level).
