Hey, thank you for playing! I can't take credit for the save system as it is built-in within the Ren'py engine that I used for the visual novel. The overlayed buttons was my mistake, I only realized that after I submitted the game. The game as being said to others in the comment, should provide minigames, for example, players has to hack the machine/camera on their own by solving a puzzle but, I don't have the time to implement that so I chose to focus on the story alone with a little branching. Talking about branching, I removed 2 plots from the story due to the limited time I had left. I will include them in post-jam updates along with multiple endings as people already asking me for that (lol). I wasn't really sure if my game really fits the concept or the theme of this jam. Personally, I joined for experience and to challenge myself, I will say it was worth it and I'm glad you have good experience with the visual novel!
