oooh I see some good potential here.
SFX: this would have really brought this up a notch. I was particularly confused with the button to move the turret, I wasn't sure what the box was and I pressed e on it but my character was in the way of the line moving so I diddn't visually see it move. Hearing the click of the button - or the turret starting up/rotating would have mitigated this!
Tutorial: totally needed for this - even just text on screen would have helped!
Pacing: Other comments suggest its too slow, but I actually liked the pace. to me it felt like it was setting the mood and tone for the game, but that being said it should feel a little more obvious that you are in a cutscene
Artwork: I actually really enjoyed the art in the game
Will follow and hope to see this updated after the jam! Keep it up!
