💬 Developer’s Note

Open Close Door is an indie project I’m creating alone in my free time — purely out of love for classic retro FPS games.
Don’t expect a massive AAA production, but if you appreciate the authentic atmosphere of 90s shooters and handcrafted content, I believe this game will grab you.
Every wishlist and bit of support means a lot to me. 🙏
