OK this Jam is really wild. I already "played" an PDF and now a PNG?! This is crazy.
I like the idea. I first thought you uploaded the wrong thing LMAO, but here we are playing a neat little dice game.
You could've just included a dice simulator, where all calculations are made for you. But it has its own appeal! I picked an online dice simulator since I don't have a 4 sided dice.
I got really lucky on my play through with a couple of 6. So I managed to beat it in 6 days total.
Play through summary (for people struggling with the rules):
Current FUNCTION: 3 + 6 = 9
Day 1: REP 6, MAL 2 (ignored since REP 6) => FUNCTION: 9 + 6 = 15
Day 2: REP 1, MAL 3 (doubled since REP 1) => FUNCTION: 15 - 5 = 10
Day 3: REP 6, MAL 1 (ignored since REP 6) => FUNCTION: 10 + 6 = 16
Day 4: REP 3, MAL 2 => FUNCTION: 16 + 1 = 17
Day 5: REP 3, MAL 3 => FUNCTION: 17 + 0 = 17
Day 6: REP 6, MAL 4 (ignored since REP 6) => FUNCTION: 17 + 6 = 23
Ending: Decent Living
