Yeah, I was kinda just banking on the player learning the room/powerup icons quickly since there's not too many, but I'll consider your suggestion. Good point on the item descriptions too, it might be better if time paused while reading them. Thank you for the feedback!
For the source code, I uploaded the project to git so you can check it out. I'm not the best coder and I'm sure there's plenty of spaghetti and bad practices here but it works lol.
