Super glad to hear you could actually add my suggestions! I try to not just point out problems but also give actionable steps to take, but looking back I realize that I might have been a little... wordy. I just really like talking about game design and I see lots of potential in your game especially, believe me that I could talk about game development for hours.
I've always felt like there's a lack of SCP games out there, and the ones that do exist are great - don't get me wrong, but all kinda feel like Containment Breach without really capturing what made the original CB so iconic. This is what originally inspired me to start working on my own SCP game, and what led me to find out about this game! I don't want to make you feel too much pressure to finish the game, but considering I myself make up a sizeable portion of this game's fanbase, I suppose that's part of my job. As long as it's still gratifying to work on I really want to know where this game goes next.
If you already have or have any plans to make a Discord server for the game, I'd love to join it! None of my current friends are really into game development or SCP at all so it'd be a good place for me to show off my own game, as well as keep helping with yours of course! If not, I'll still keep up with any developments you post here on itch!
