Overall I do a ton of rupee grinding in level 2. Namely ropes have a high drop rate for blue rupees. Thus I battle them over and over. I made my first mistake here by not grinding enough rupees. Overall I'm happy with this run
This is my no sword run for Zelda 1, with no save states. I make so many mistakes that I know I can improve. ideally I should have had level 5 in one shot without retrying. I'm not sure if level 6 is possible without a bomb upgrade, but may be possible to get the wand with only 8 bombs. A perfect room means you'd only use 3 bombs in the first room, three bombs in the wand room and one bomb through the wall. thus using 7 bombs.
