Glitter Gulch Mine Shooting Game

I think I may be stupid and I'm trying not to Google any answers because I managed to beat BK, BT and DK64 without it as a young kid.

As a 30+ year old adult, after several tries I cannot find the final dynamite! I'm listening for it and the rooms are hard to tell apart because they are all wood and dirt. I feel very disappointed in myself since I think I have brain fog that really damaged my brain. So I have a harder time solving things now or I'm just getting older.

Anyone else feel me on this or am I alone?
