Holy shet man did you make all of this yourself in 2 days!? That was frkin EPIC man, really NAILED the GAME FEEL!.
The lower framerate blood effects and water ripples, the freezeframes (although sometimes there were too many freeze frames and it genuinely felt like the game was dropping frames and lagging) the screenshake, u even got death sounds and stuff for the enemies and player.
Also cube falls off if you rush through the level to the very end lol but for 2 days this is already too much man! Also there is even joystick support! it was better when played with joystick tbh, felt more immersive
Did you use some asset/extension for the freezeframe and screenshake or did you code it yourself?
Also how long have you been doing gamedev? cuz all this isn't beginner level stuff you definitely are experienced
