This was a blast, which is weird since I am so not a math person and literally have dyscalcula. I guess funny animals can make me enjoy anything. I stopped for a few days after messing up on day 5, and then when I came back I realized I could simplify my calculations and note-taking with PEMDAS and i don't think i messed up a single other transaction which ruled. The final conversion was genuinely insane and I had to break out some notes for it, and the final paycheck... was kind of comically sad, the poor thing. I also noticed that the coins given aren't the same when you replay a day (I restarted that day 5 to have a perfect run) which is pretty great for replayability, and makes me wonder if the paycheck is always the same or if it changes according to anything. Some dialogue also made me wonder about that, but I figure that the game isn't really going to bother tracking if I was actually getting the A rank every day, especially when starting from the day select.
Anyways, really charming and cool!! My brain hurts but I feel satisfied :)
