To be honest... the strength increase of enemies and bosses is quite good, but the struggling system is quite disgusting... It is impossible to directly hold down [Z] to struggle, which means that all bosses cannot make any mistakes. As long as you make a mistake, some bosses will squeeze you out of the map or enter an infinite escape state, making it impossible to fight and unable to return to the base halfway. This means that you must complete a level in the state of [0 supply], whether it is speed level or boss level... This is not a mod that can be played normally, it is just a mod made to increase difficulty, especially the poor operation in the original game, which causes the difficulty of this mod to increase exponentially. I doubt if the mod has been tested before its release
