Great little game! Loved the vibe and the keyboard smashing lol. Can't wait to see more! I do have a little bit of feedback.
1. Keeping control of the lungs feels kind of random and almost like an afterthought. I think u could explore that mechanic further and enhance it. Maybe it happens only every 60 seconds and u made it something like the heartbeat minigame from Roblox Doors sort of like friday night funkin. Here's a vid of someone doing it.
2. It didn't feel like I had a lot of control over my stress. Felt like I was just kinda doomed to dying eventually.
However I feel like this game is an amazing concept and can't wait to see it further developed :D
