Congrats on the great submission here 🎉
I really enjoyed playing this game. The voice acting was great, the different puzzles were fun to play, and all the sound effects really helped build an atmosphere. I ended up having to play it twice (lost a lot of time to listening to the dialog, so I blew up the first time, and then won on the second run), but I enjoyed both runs.
My feedback would probably be the same as others here. I think pausing the timer (even if you kept the bomb ticks going) would be a totally acceptable (even if it would be non-diegetic). You could also potentially remove the 10 second penelty for missing (you already aren't making progress, so I don't know that you need an additional penelty on top).
Again, really great job here, so thank you for making and sharing this game!
