I really like that mushroom idea. The treasure all adds up to your dollar score at the end... which you can't spend. Everyone really cares about those high scores, after all =/
That's cooking up an idea in my head to spend it on post-game content as a reward. Build-your-own pyramid?
The blue crystal will get replaced by the orange crystal soon, so go nuts I say (you can still shoot your pistol with the crystal equipped, you know). It can be handy for ooze encounters. (btw, which ladder will you take first?)
I think you're getting better at writeups, but this obviously isn't meant to be a thorough review since you aren't getting entire conversation trees. It's more like a casual feel-as-you go playthrough. I like that. PiD could've been great if it were introduced 20 years into the future during the streaming era. Stupid 5 nights at Freddies and Undertale's got nothing on blind PiD playthroughs.
