Each day the prices change randomly (I had some other ideas that didn't happen for price fluctuations) with an increasing bonus for each scoop beyond 4 (I think, not at the pc with the source), something like 5% but there absolutely could be some bugs there, plus each flavor counts as a scoop (because I ran out of time to correctly count scoop flavors). I had intended to have a system where different flavors affected neighboring cones but none of that manifested.
The first idea was a rhythm game that you're beatboxing for breakdance competition and you need to be silent when a freeze is performed. For better or worse I always push some technical aspect; I did a series of experiments to see if I could identify different drum mouth-noises that went well but when I got all the pieces together I just couldn't reliably do it. I briefly thought about doing a typical rhythm component but decided against it because I knew I didn't have enough time to do make the breakdance portion cool so it would just be a kinda-normal rhythm game with bad visuals and I like to use jams for weird experiments (though am thankful that many people make so many different things with different goals). I'm in PDT so started ice cream farmer around 8pm on Saturday with the submission time of 1pm the next day. I probably got 5ish hours before bed, then another couple of hours before the deadline. Initially I brainstorm several ideas and I'll often still have ideas for the things I didn't do. Of the other ideas, ice cream farmer was the most fleshed out so that's what I went with.
