I made a VERY SHORT game using Bitsy. And it's so normal.
Here's a GUIDE! A very quick and cryptic one, in fact:
Ending 1: Talk to someone. Easy.
Ending 2: Don't talk. Find a weird looking block, go to the next room. THEN talk.
Ending 3: Grab three Es. Go to the next room. Grab all the Es EXCEPT the top one. THEN grab the top one. Go to the house. Proceed.
Ending 4: Get to the house room without grabbing every E.
And some quick answers: yes, no, no, yes, almost, maybe, yes, no. E.
