Cool game!
I had to tab out and look on the itch page how the controls worked. Having some sort of in-game tutorial or how to play is nice I think.
Regarding SFX, try and keep the time before the peak as short as possible, like the buttons in the menu had some nice sfx, but they came quite late, and also the doors in game had their sound peak when I had already gone a bit into the next room.
It would have been nice with some feedback on taking damage, and maybe also some way of escaping the cool enemy robots.
I really liked the robot model! Great job there!
I think without background music, some footsteps or ambience would have added a ton to the game.
Congratulations on your first solo game! It has its qualities, going solo :)
