what divination method(s) was used?
Process

I wrote headers for each portion of my game, act1, act2 etc. and 3 possibilities for each, just the first thing that came into my head. The quest ideas were mostly based on stuff that was sitting on my desk at the time.

I then rolled my d3, which is just a d6 which someone has only furnished with the numbers 1-3 making it strictly less useful than a normal d6. Anyway I rolled once for the quest, 2 acts, boss and outcome, and made the game that came out of it - enjoy!

I've put screenshots of the possible options on the itch page for the game, but I'll list them here too:

Quest:
Retrieve...
1. Aspidistra
2. Paracetamol
3. Default Bitsy Tea

Act1
1. Overthrow tyrannical space empire
2. Restore dinosaur emperor to his rightful throne
3. fucking crap underwater level

Act2
1. betrayal by party memeber
2. tragic death of sir Frogsalot
3. absolutely loads of furious dogs

Final Boss
1. Gastro-intestinal worm
2. corporate skeleton
3. bitsy cat

Outcome
1. Victory!
2. Annoyingly vague conclusion
3. Twist - you fucked it
