I think you should be checking secret rooms if you skip treasure rooms for planetariums. Also a great item for planetarium hunting that appears in the shop called "dream catcher", which let's you see the next floors boss and treasure room item during the level transition. This way you know if there's a quality 4 item you don't want to skip. Regarding your feeling of progression, just know that even if you don't unlock something during a run, you still learn the game and have made a lot of progress in that regard!
I normally try for planetariums but unfortunately my luck is ungodly levels of poor with them so I just decided to go with more power in the start. Also thank you so much for the kind words! :)
Honestly i'm not proud at all of how this stream sounds. Thats why it has no tags or anything. I would normally re-record it but we made good progress in this stream and i didn't want to ruin any first impressions I had during the stream.
After some thinking I've decided that not only will I not use the gun from Russian roulette I will also not use Buckets. I did save scum for him and it kind of ruins the point of the game. However I did win 3 games in a row on my first attempt so I'll also cough up like half the mags I won and replace it with around the 300 I won from the first three rounds. Hope this makes up for save scumming
