first things first not sure if its missing textures or something but in the future PLEASE dont use high contrast colors like bright pink for your main menu, as its really hard on the eyes, also a minor bug but the mouse sensitvity's slider is invisible.
as for the actual game, i love the idea of a swarm shooter where you use your past selves to manage all the enemies but the execution is very flawed, due to bugs like the enemies not having a projectile and shooting pink orbs that block your movement or inconsitencies in the ai between the runs meaning that your "clones" dont really kill the enemies they should
overall interesting concept but flawed exectution
