Thanks for the feedback. I was just lucky I had quite a lot of free time for this jam. I couldn't take full credit for the audio since I use a free external audio website. The guides were technically added last minute so I'm happy someone could actually comprehend my ramblings.
For the security's difficulty, they were initially supposed to have a much wider field of vision. But since more security guards will show up as the player progresses, the stages were impossible to clear by then.
As for the cover image, by the time I'm uploading the project it was close to midnight in my timezone so I got lazy and just screenshot the main menu, lol.
